postgres-xc-general Mailing List for Postgres-XC

Hello Afonso;

Thanks a lot for this presentation with your experience with XC.   I
visited the site and the proceedings looks only for the attendees.
Hope you can disclose your talk slide.

we are proud to announce our participation in E-Learn 2014

I might have been wrong.   My colleague tried to do it with Heartbeat and couldn’t find how to do it.   Corosync may be better to handle it.

Thanks.

Hi Suzuki-san,

Yes, we have written custom resource Corosync/Pacemaker agents for failover of GTM to GTM-standby and also for failover of datanodes in Postgres-XL.

As Mason mentioned, the setup is a little complicated, but doable and yes we need to be a little careful about too eager failover.

Nikhils

We have configured with Corosync/Pacemaker. It is complex, however.

In HA, I don’t think Corosync/Pacemaker can deal with XC configuration, where many components are interrelated and they are HA-aware.    At present, Corosync/Pacemaker works well for HA-unaware components with master/slave pair model.   XC configuration is more complicated than what they can deal with.

You may find the Holy Grail here:
http://sourceforge.net/projects/postgres-xc/files/Presentation/

Just to provide a bit more background information to save some time for TL;DR cases-

Performance:

OLTP: coordinators add about 30% overhead. For linear scalability, we would expect 10 nodes to have about 7x performance compared to vanilla PostgreSQL. Instead it is 6 - 6.4 in DBT-1 tests, a TPC-W like benchmark.

OLAP: it depends on your schema, but if denormalized and quite simple, you can expect pretty much linear scalability. With a more complicated schema or queries, more nodes may perform worse than native PostgreSQL.

HA:

There is no automatic failover. You can set up standbys of key cluster components, and fail them over manually. An alternative is to write your own monitoring and failover, or use Corosync/Pacemaker. If acceptable in your environment, it may even be preferable to manually failover to prevent false positives and having to deal with failback.

I hope that helps.

There are no differences with Postgres itself, so here is a good reference:
http://www.postgresql.org/docs/devel/static/dynamic-trace.html
In short, the RPMs you got need to be compiled with --enable-dtrace set at
./configure. Not sure if those RPMs have it set though... Run this command
to be sure after installing the RPMs:
pg_config | grep CONFIGURE.
‍
Note that this is a mailing list for Postgres-XC, not Postgres-XL, even if
I don't mind much..

Do you mean interaction between different XC clusters?   If so, it is
outside XC scope at present.    You may need FDW or blink, which are
not enabled in XC yet.

How to enable dtrace  after installed postgresql-xl in .rpm ‍

First,I installed postgresql-xl  in .rpm not source code.Then I need to enable dtrace to trace ‍dynamicly,How should I do?‍

Hi, i'm studying informatics and we are doing an investigation of
postgres-xc.
I searched information about that everyware and it isn't enough for making
a presentation.
Can you give me a little more information or a document in where I
could see more
technical specifications??
Thanks for all !!!

Santiago Ibarbia.
Spain

I see...
But, let's suppose  if I have XC Cluster on site "A", and that Cluster also
connect with other site "B", which has it own Cluster.

Then, when Site "A" goes off line,  I suppose that when connection back on
line, there's some updates spread to cluster. Or am I wrong thinking like
that?
I'm just trying to understand...

Thank you

Gilberto Ferreira

Postgres-XC is based upon tightly coupled distributed database mode, which means it generally assumes all the nodes are up and available.

In reality, if failed node is not involved in a transaction, it will be successful.   If you try to update a shard at failed node, or you try to update replicated table which the failed node is involved, or if you try to issue DDL which is supposed to propagate to all the nodes, such transaction will fail.   It is quite hard for XC to allow only partial DDL propagation because this will very easily make whole cluster inconsistent when the failed node is up and back.

Hope your application meets this behavior.

What I looking for is using Potsgre-XC on distribuited sites... Once this site get off line for any reason, link Local Link failure or Cluster Link failuer, local application can continue works and once the link get back on line, the Postgres-XC sync the local difference with others nodes/databases on the others site...

I need to know if this will be nice, if I use normal adsl...

Hell;

Abbas, thanks for the quick response.

To start with, pgxc_ctl primer will be a good starting point.   Pgxc_ctl is postgres-xc cluster configuration/operation utility.

Tutorial is available at https://sourceforge.net/projects/postgres-xc/files/Pgxc_ctl_primer/

I’m afraid 1.0.x is a bit old.   Why don’t you start with 1.1 or 1.2?   1.1 and 1.2 are almost identical from XC-specific features point of view.   1.2 comes with new PG 9.3 features.

Postgres-XC document is available online.   You can find links at https://sourceforge.net/p/postgres-xc/xc-wiki/Documentation/

Pgxc_ctl reference is included in it.

Cheers;

Your application can connect to any of the coordinators.

If you mean the link between application and the cluster you should be OK.

Yep

I'll work with 1.2 version... 1.0.4 was just for test purpose and to
understand the concept...
BTW, can work with ADSL as Internet Link, like 30 MBPS or dedicate link is
recommend?
I know there's some others specs that I need to take in mind, like
processors, memory, and so on...
But  my doubt is if I work with normal ADSL the DB will be work properly...

Thanks

Hell;

Abbas, thanks for the quick response.

To start with, pgxc_ctl primer will be a good starting point.   Pgxc_ctl is postgres-xc cluster configuration/operation utility.

Tutorial is available at https://sourceforge.net/projects/postgres-xc/files/Pgxc_ctl_primer/

I’m afraid 1.0.x is a bit old.   Why don’t you start with 1.1 or 1.2?   1.1 and 1.2 are almost identical from XC-specific features point of view.   1.2 comes with new PG 9.3 features.

Postgres-XC document is available online.   You can find links at https://sourceforge.net/p/postgres-xc/xc-wiki/Documentation/

Pgxc_ctl reference is included in it.

Cheers;
