From: Andrei M. <and...@gm...> - 2011-05-24 17:18:59

Hi Abbas,
I looked at the code and see that for some data types the compute_hash()
returns not a hash code, but original value:
+ case INT8OID:
+ /* This gives added advantage that
+ * a = 8446744073709551359
+ * and a = 8446744073709551359::int8 both work*/
+ return DatumGetInt32(value);
+ case INT2OID:
+ return DatumGetInt16(value);
+ case OIDOID:
+ return DatumGetObjectId(value);
+ case INT4OID:
+ return DatumGetInt32(value);
+ case BOOLOID:
+ return DatumGetBool(value);
That not a critical error and gives a bit better calculation speed but may
cause poor distributions, when, for example, distribution column contains
only even or only odd values.
Some node may have many rows while other may not have rows at all. I suggest
using hashintX functions here.
And another point: Oid's are generated on data nodes, does it make sense to
allow hashing here, where it is supposed the value is coming from
coordinator?

I don't think it is a good idea that they have to know that they should change all of their application code and add casting to make sure it works like they want. I think people are just going to get themselves into trouble. I strongly recommend disabling distribution support for some of these data types.

Leave XC aside this test case will produce same results in plain postgres for this reason. The column actually does not contain 0.666666666666667, what psql is showing us is only an approximation of what is stored there. select * from float1 where a = 2.0/3; would however work. 2ndly suppose we have the same test case with data type float4. Now both select * from float1 where a = 0.666666666666667; and select * from float1 where a = 2.0/3; would show up no results both in PG and XC. The reason is that PG treats real numbers as float8 by default and float8 does not compare to float4. select * from float1 where a = cast (2.0/3 as float4); would therefore work. Any user willing to use float types has to be aware of these strange behaviors and knowing these he/she may benefit from being able to use it as a distribution key. > Looking at the plan it tries to take advantage of partitioning: > > mds=# explain select * from float1 where a = 0.666666666666667; > QUERY PLAN > ------------------------------------------------------------------- > Data Node Scan (Node Count [1]) (cost=0.00..0.00 rows=0 width=0) > (1 row) > > I think we should remove support for floats as a possible distribution > type; users may get themselves into trouble. > > > There may be similar issues with the timestamp data types: > > mds=# create table timestamp1 (a timestamp, b int) distribute by hash(a); > CREATE TABLE > mds=# insert into timestamp1 values (now(), 1); > INSERT 0 1 > mds=# select * from timestamp1; > a | b > ----------------------------+--- > 2011-05-24 08:51:21.597551 | 1 > (1 row) > > mds=# select * from timestamp1 where a = '2011-05-24 08:51:21.597551'; > a | b > ---+--- > (0 rows) > > > As far as BOOL goes, I suppose it may be ok, but of course there are > only two possible values.

I am not sure some of these data types are a good idea to use for
distributing on. Float is inexact and seems problematic
I just did a quick test:
mds=# create table float1 (a float, b float) distribute by hash (a);
CREATE TABLE
mds=# insert into float1 values (2.0/3, 2);
INSERT 0 1
mds=# select * from float1;
a | b
-------------------+---
0.666666666666667 | 2
(1 row)
Then, I copy and paste the output of a:
mds=# select * from float1 where a = 0.666666666666667;
a | b
---+---
(0 rows)
Looking at the plan it tries to take advantage of partitioning:
mds=# explain select * from float1 where a = 0.666666666666667;
QUERY PLAN
-------------------------------------------------------------------
Data Node Scan (Node Count [1]) (cost=0.00..0.00 rows=0 width=0)
(1 row)
I think we should remove support for floats as a possible distribution
type; users may get themselves into trouble.
There may be similar issues with the timestamp data types:
mds=# create table timestamp1 (a timestamp, b int) distribute by hash(a);
CREATE TABLE
mds=# insert into timestamp1 values (now(), 1);
INSERT 0 1
mds=# select * from timestamp1;
a | b
----------------------------+---
2011-05-24 08:51:21.597551 | 1
(1 row)
mds=# select * from timestamp1 where a = '2011-05-24 08:51:21.597551';
a | b
---+---
(0 rows)
As far as BOOL goes, I suppose it may be ok, but of course there are
only two possible values. I would block it, or at the very least if
the user leaves off the distribution clause, I would not consider BOOL
columns and look at other columns as better partitioning candidates.
In any event, I am very glad to see the various INT types, CHAR,
VARCHAR, TEXT, NUMERIC and DATE supported. I am not so sure how useful
some of the others are.
Thanks,
Mason

Support for single-prepared PL/PGSQL functions
This commit fixes primarily problems like in bug 3138450
(cache lookup for type 0) where XC was not able to set up
plpgsql parameter values because values were not correctly fetched.
This commit does not yet solve the special case of multiple
uses of same plpgsql datum within a SQL command.
PL/PGSQL functions using subqueries are out of scope for
the moment due to XC's restrictions regarding multi-prepared
statements.

This patch fixes a problem in XC that INSERTS/UPDATES in catalog
tables were not possible from psql prompt.
The problem was in XC planner. XC planner should first check if
all the tables in the query are catalog tables then it should
invoke standard plannner.
This change enables us to remove a temp fix in GetRelationLocInfo.
Also a query is added in system_views.sql to add a corresponding
entry in pgxc_class.
RelationBuildDesc is asked to include bootstrap objetcs too while
building location info.

commit b931435761b21f27aef8aca7e7e319bd0bee3a3a
Author: Abbas <abb...@en...>

This patch makes the group by on XC work. The changes are as follows
1. The application of final function at coordinator is enabled though AggState execution.
Till now final function was being applied during execution of RemoteQuery only,
if there were aggregates in target list of remote query.
This only worked in certain cases of aggregates (expressions involving aggregates,
aggregation of join results etc. being some of the exceptions).
With this change the way grouping works the same way as PG except
a. the data comes from remote nodes in the form of tuples
b. the aggregates go through three steps transition,
collection (extra step to collect the data across the nodes) and finalization.
2. Till now, the collection and transition result type for some aggregates like
sum, count, regr_count were different.
I have added a function int8_sum__to_int8() which adds to int8 datums and
converts the result into int8 datum. This function is used as collection function
for these aggregates so that collection and transition functions have same result types.
3. Changed some of the alternate outputs to correct results now that grouping is working.
Commented out test join, since it's crashing with grouping enabled.
The test has a query which involves aggregates, group by and order by.
The crash is happening because of order by and aggregates.
Earlier the test didn't crash since GROUPING as disabled and the query would throw error,
but now with grouping is enabled, the crash occurs. Bug id 3284321 tracks the crash.
4. Added new test xc_groupby.sql to test the grouping in XC with round robin and
replicated tables with some simple aggregates like sum, count and avg.
All work done by Ashutosh Bapat.

commit 49b66c77343ae1e9921118e0c902b1528f1cc2ae
Author: Abbas <abb...@en...>
Date: Tue May 24 17:06:30 2011 +0500
This patch adds support for the following data types to be used as distribution key
INT8, INT2, OID, INT4, BOOL, INT2VECTOR, OIDVECTOR
CHAR, NAME, TEXT, BPCHAR, BYTEA, VARCHAR
FLOAT4, FLOAT8, NUMERIC, CASH
ABSTIME, RELTIME, DATE, TIME, TIMESTAMP, TIMESTAMPTZ, INTERVAL, TIMETZ
A new function compute_hash is added in the system which is used to
compute hash of a any of the supported data types.
The computed hash is used in the function GetRelationNodes to
find the targeted data node.
EXPLAIN for RemoteQuery has been modified to show the number of
data nodes targeted for a certain query. This is essential
to spot bugs in the optimizer in case it is targeting all nodes
by mistake.
In case of optimisations where comparison with a constant leads
the optimiser to point to a single data node, there were a couple
of mistakes in examine_conditions_walker.
First it was not supporting RelabelType, which represents a "dummy"
type coercion between two binary compatible datatypes.
This was resulting in the optimization not working for varchar
type for example.
Secondly it was not catering for the case where the user specifies the
condition such that the constant expression is written towards LHS and the
variable towards the RHS of the = operator.
i.e. 23 = a
A number of test cases have been added in regression to make sure
further enhancements do not break this functionality.
This change has a sizeable impact on current regression tests in the following manner.
1. horology test case crashes the server and has been commented out in serial_schedule.
2. In money test case the planner optimizer wrongly kicks in to optimize this query
SELECT m = '$123.01' FROM money_data;
to point to a single data node.
3. There were a few un-necessary EXPLAINs in create_index test case.
Since we have added support in EXPLAIN to show the number of
data nodes targeted for RemoteQuery, this test case was producing
output dependent on the cluster configuration.
4. In guc test case
DROP ROLE temp_reset_user;
results in

This is the rety of cancelled commit for gtm-proxy reconnect.
This is the first part of the commit. With GTM-Standby, this commit
works for the normal case. This also includes all the infrastructure
to run "reconnect" including signal hander, backend command backup
and release, signal detection and backend command recovery.
Next work includes add real "reconnect" and node registration both for
worker thread and main thread so that we can test "reconnect".

commit 1dc1b90e434dbe56438dec9dfa8887de1767d457
Author: Koichi Suzuki <koi...@gm...>
Date: Mon May 16 18:30:02 2011 +0900
This commit corrects the initial notify for each document source to mark
what section is from PostgreSQL and needs review/revision for Postgres-XC.
Next work is to review each section and revise it as Postgres-XC
documentation.
This will be done in the following order:
1. Installation/Cluster configuration/Cluster admninistration,
2. Statements,
3. Tutorials,
4. Application interface.
All the source files are affected.

commit 7c0fb4e4bf34f558697ee864e68b01dc05f08e81

XC Watcher and Configurator
Configurator is a utility that can be used to setup a Postgres-XC cluster
automatically. Based on Ruby and a global YAML configuration file, it is in charge of
parsing the global file, make postgresql.conf, indent and pg_hba.conf,
and then distribute each postgreSQL file automatically to each node.
XC watcher is a module using XCM flag information to gather the status of nodes
in the cluster and what kind of action is necessary in case a node fails.
This module takes into account Datanode, Coordinator, GTM, GTM-Proxy and GTM-Standby.

This is the second commit of Postgres-XC documentation. Contents of the commit is as follows:
1) For sections just from PostgreSQL and not reviewd yet, added notice that this need further review and revision. Notice will be found in the file pgnotice.sgmlin.
2) First revision work on "installation". This is still WIP.
To include notice in 1) almost all the files are modified. So far, we can generate html and man with this commit.

Support for single-prepared PL/PGSQL functions
This commit fixes primarily problems like in bug 3138450
(cache lookup for type 0) where XC was not able to set up
plpgsql parameter values because values were not correctly fetched.
This commit does not yet solve the special case of multiple
uses of same plpgsql datum within a SQL command.
PL/PGSQL functions using subqueries are out of scope for
the moment due to XC's restrictions regarding multi-prepared
statements.

This patch fixes a problem in XC that INSERTS/UPDATES in catalog
tables were not possible from psql prompt.
The problem was in XC planner. XC planner should first check if
all the tables in the query are catalog tables then it should
invoke standard plannner.
This change enables us to remove a temp fix in GetRelationLocInfo.
Also a query is added in system_views.sql to add a corresponding
entry in pgxc_class.
RelationBuildDesc is asked to include bootstrap objetcs too while
building location info.

commit 95fbb1a7742ef7cb0698875dbb3ad758499c21c7

This commit fixes problem in node registration, combined with GTM-Standby.
In the previous code, in MSG_NODE_REGISTER command, hostname was optional, depending upon type of the node to register. It is misleading. Because hostname embedded in the message is obtained using the same function, host name is now mandatory in this message for simplification.
Second fix is selecting transaction slot from GTM inside database in GTM-Standby. Original code tested if GXID is invalid. Instead, we should test gti_in_use, which is also used to vacant slot.
Third fix is adding status of each sequence in backing up by GTM-Standby.
In this way, now GTM-Stanby can be connected to GTM-ACT normally. Next fix will include tweak in source code of GTM, including adding comments, and GTM-Proxy reconnect to promoted GTM-Standby.

commit baa29ae9435f03d3495828c78d89c6b235e61bb0
Author: Abbas <abb...@en...>

This patch makes the group by on XC work. The changes are as follows
1. The application of final function at coordinator is enabled though AggState execution.
Till now final function was being applied during execution of RemoteQuery only,
if there were aggregates in target list of remote query.
This only worked in certain cases of aggregates (expressions involving aggregates,
aggregation of join results etc. being some of the exceptions).
With this change the way grouping works the same way as PG except
a. the data comes from remote nodes in the form of tuples
b. the aggregates go through three steps transition,
collection (extra step to collect the data across the nodes) and finalization.
2. Till now, the collection and transition result type for some aggregates like
sum, count, regr_count were different.
I have added a function int8_sum__to_int8() which adds to int8 datums and
converts the result into int8 datum. This function is used as collection function
for these aggregates so that collection and transition functions have same result types.
3. Changed some of the alternate outputs to correct results now that grouping is working.
Commented out test join, since it's crashing with grouping enabled.
The test has a query which involves aggregates, group by and order by.
The crash is happening because of order by and aggregates.
Earlier the test didn't crash since GROUPING as disabled and the query would throw error,
but now with grouping is enabled, the crash occurs. Bug id 3284321 tracks the crash.
4. Added new test xc_groupby.sql to test the grouping in XC with round robin and
replicated tables with some simple aggregates like sum, count and avg.
All work done by Ashutosh Bapat.

commit a3170920c368411b1b9a9e261088a21009fcf74e
Author: Koichi Suzuki <koi...@gm...>
Date: Wed May 4 00:51:00 2011 +0900
This is another fix in GTM-Standby mainly in initial backup of
transaction and sequence status. I have reviewd each serialize and
deserialize and fixed potential problems, mainly in handling character
strings.
Although there are a couple of remaining issues which may cause
problems in further test, now GTM-Standby initial backup seems to
work. It still have a problem to register itself to GTM-ACT. This
will be reviewed soon for the fix.

commit 23a4fb8b47248782417a97253bd83e13ec1db1b3
Author: Koichi Suzuki <koi...@gm...>
Date: Tue May 3 13:35:40 2011 +0900
This is to add "virtual class" memory allocation/deallocation
especially for gtm/client submodules.
Beckground: GTN-Standby backs up GTM-ACT data in synchronous way.
gtm/client submodule do this work. Because this submodule takes care
of send/receive current GTM-ACT status, gtm/clinet occasionally has to
allocate the memory as needed.
Because gtm/client should run as a part of GTM/GTM-Standby, GTM-Proxy,
independent application (such as pgxc_clean) and postgres, famous
"palloc" series of utility calls has to be different routine depending
upon its running environment.
Implemnetation can be done by asking the environment (mcxt.c or
correspoinding source) to provide entries of such memory allocation
functions.
Framework of this virtualization can be found in gen_alloc.h.
Postgres (e.g.coordinator and datanode) implementation is in
src/backend/utils/mmgr/mcxt.c. GTM/GTM-Standby/GTM-Proxy
implementation is in gtm/common/mcxt.c. pgxc_clean implmentation is
in src/pgxc/pgxc_clean/common.c.
palloc.h's are modified to reflect these changes.
gtm_serialize.c and gtm_serialize_debug.c modifications are to include
memory allocation in transaction information deserialization (need to
allocate memory dynamically for each snapshot).
Added/modified files are:

commit 4f179ba15eac0e6416cc76693fc6c432e432488c
Author: Koichi Suzuki <koichi@ks-ubuntu-notepc.(none)>
Date: Tue May 3 13:09:59 2011 +0900
This is to add "virtual class" memory allocation/deallocation especially for gtm/client
submodules.
Beckground: GTN-Standby backs up GTM-ACT data in synchronous way. gtm/client submodule
do this work. Because this submodule takes care of send/receive current GTM-ACT
status, gtm/clinet occasionally has to allocate the memory as needed.
Because gtm/client should run as a part of GTM/GTM-Standby, GTM-Proxy, independent
application (such as pgxc_clean) and postgres, famous "palloc" series of utility
calls has to be different routine depending upon its running environment.
Implemnetation can be done by asking the environment (mcxt.c or correspoinding source)
to provide entries of such memory allocation functions.
Framework of this virtualization can be found in gen_alloc.h. Postgres (e.g.coordinator
and datanode) implementation is in src/backend/utils/mmgr/mcxt.c. GTM/GTM-Standby/GTM-Proxy
implementation is in gtm/common/mcxt.c. pgxc_clean implmentation is in src/pgxc/pgxc_clean/common.c.
palloc.h's are modified to reflect these changes.
gtm_serialize.c and gtm_serialize_debug.c modifications are to include memory allocation in
transaction information deserialization (need to allocate memory dynamically for each
snapshot).

commit a877e0769b83719b446d15a243e14b05700f975a
Author: Abbas <abb...@en...>
Date: Mon May 2 19:16:38 2011 +0500
This patch fixes TWO bugs 3273569 & 3243469
The problem was that prepared transactions were not being listed in
the system view pg_prepared_xacts.
The reason was that in XC transactions are not prepared on the coordinator and
hence the function pg_prepared_xact does not return any. The main worker function
GetPreparedTransactionList which is supposed to return an array of prepared
transactions for the user level function pg_prepared_xact, always finds ZERO
in TwoPhaseState->numPrepXacts, since the transaction was never prepared on the
coordinator.
The solution was to ask data nodes, where the transaction was actually prepared.
All data nodes may not be involved in all transactions hence we have to ask
all data nodes in any case.
In order to implement this solution we created two schemas,
__pgxc_datanode_schema__ & __pgxc_coordinator_schema__
one for data nodes and one for coordinators respectively.
Next these schemas were added to the default search path in coordinator
as well as on data node.
Hence the default search path on coordinator is
"$user",public, __pgxc_coordinator_schema__
and on the data node is
"$user",public, __pgxc_datanode_schema__
Next we created a table named pg_prepared_xact in the schema __pgxc_coordinator_schema__
with the same fields as the old view pg_prepared_xact.
and we created the old view pg_prepared_xact in the schema __pgxc_datanode_schema__.
Now when a query for the view pg_prepared_xact is launched on the coordinator,
it knows it is a table distributed in round robin fashion on all data nodes and hence
it generates a query to ask all data nodes.
The only difference will be that if we have two data nodes and the transaction was
prepared on both we will get two rows for it which is correct. If one row per
transaction is required all that is required is to add distinct in the query.
A few changes in this patch are due to the following two limitations
which are not addressed by this patch.
1. create table in system_view.sql does not enter a corresponding row in pgxc_class.
2. We need to ROLLBACK manually after a PREPARE TRANSCATION fails due to name duplication.
The prepared_xacts.sql test case now passes, and hence successive regression runs are
now possible.
