What do you mean by “multi master”? If you mean “multi master replication”, it is reasonable not to expect write scalability. XC will provide read scalability in this case though. XC’s write scalability is achieved by both GTM (Global XID) and the combination of table sharding and replication. Stable tables should be replaced, while frequentlly-updated tables should be shared. Hope your application matches XC. --- Koichi Suzuki 2014/03/27 20:24、Juned Khan <jkh...@gm...<mailto:jkh...@gm...>> のメール： Hi Koichi, As of now what i am trying to do is, i want to setup pgxc for one state. but in future this number of state will be increased upto five.

Hi Mason That is correct mailing list helped me a lot, and i am very thankful to everyone. Yeah earlier i have asked about this requirement and received good response and advices but the point which you have mentioned that is noticeable, i can not ignore that i should think about this many points before moving ahead.

It has not been tested with XC yet. pg_upgrade handles catalog upgrade and I don’t think it handles pgxc_* catalogs. Unfortunately, we’ve not done pg_upgrade extension to XC.

Hi Mason, OK, that is not too much, regular PostgreSQL could work. Are a lot of those reads? Perhaps you can use PostgreSQL with streaming replication and do reads from a local hot standby, but writing to a remote master. It would have to be ok though that writes are not permitted if the network is down, as well as accepting that for those reads it may not be the latest version of the row/tuple, and the writes will incur latency. The other things you could do is, if your writes are mainly inserts is to write to local tables when the network is down, and then write these to the remote master once it is up again for this scenario what application i should use, what powerful and stable application you do suggest to achieve this ? As per my requirement i would have two database server on each state (MASTER and SLAVE) so i have to write those data on Central server.

Hi Mason, how many transactions per second? there is almost 50 to 100 How much of the data needs to be replicated to all nodes and how much can be distributed? Equally, if i have two datanodes with 50 records then they should distributed equally How frequently do (reporting) queries need to look at all billion rows or a large portion thereof? 10 t0 20 times per day, we have 4 to 5 kind of CDR reports. Please suggest.

Hi All, I have installed pgxc on one of my server which is pgxc-1.1 but i had some issues with that version and those issues are fixed in latest stable(REL1_2_STABLE) so is there any automatic or manual process to upgrade it i found this link but seems this is to upgrade postgreSQL but i want to upgrade pgxc itself to latest stable http://postgres-xc.sourceforge.net/docs/1_1_beta/upgrading.html Please suggest. -- Thanks, Juned Khan iNextrix Technologies Pvt Ltd. www.inextrix.com |

Hi Koichi, Thanks you very much for your reply As i am testing with VMs and yet didn't put this on production server i can go with fixed and stable version of pgxc. https://github.com/postgres-xc/postgres-xc/tree/REL1_2_STABLE And even i am happy that i have solutions for such issues.

Thanks. I did another analysis in parallel and found the following: 1) pg_basebackup does not run with the coordinator, 2) alter node does not work correctly if it needs pgxc_pool_reload(). In this case, you should use DROP NODE and CREATE NODE instead. The log says the above. I've included all these fixes to the latest REL1_2_STABLE branch at both sourceforge and github repo. Please try. Fixes are made in pgxc_ctl. Also, please note that the master branch does not include this fix because we need to fix the above in the master anyway. To fix your problem, visit each coordinator and do the following: 1) Restore pgxc_node entries for the remote node by DROP NODE and CREATE NODE. 2) After all done, issue "select pgxc_pool_reload()" 3) Restore local node pgxc_node entry by ALTER NODE, 4) Issue "select pgxc_pool_reload()" I hope this may fix your problem without re-configuring the cluster. Otherwise, please try from the scratch with the latest pgxc_ctl. My apology for the inconvenience and appreciate for your patience and collaboration.

Is it ok for there to be an outage? I believe I also previously said XC may not be the best fit for what you are doing. You could perhaps make it work by modifying the code, but it depends on exactly what you are trying to do. You mention a billion rows, but how many transactions per second? How much of the data needs to be replicated to all nodes and how much can be distributed? How frequently do (reporting) queries need to look at all billion rows or a large portion thereof? Are writes typically done at each location for a particular set of data (regional customers)? Or is that all sites need to write to all of the data equally, that there is not a good way of splitting it up? -- Mason Sharp TransLattice - http://www.translattice.com Distributed and Clustered Database Solutions |

Hi Michel, Thank you very much for valuable response. As a solution of this problem can i use VPN or setup all components on same network ? Please suggest.

Hmmm.. it’s quite strange. Another way to collect info is to set the following in postgresql.conf for the coordinator in question. log_min_messages = debug5 log_error_verbosity = vervose It could be too novice but please do this at the coordinator your psql is connecting. Also, it will be safer to restart your coordinator to make these changes effective. Could share the result?

Don't do that. Postgres-XC is designed to work with nodes located close to each other, and OLTP applications. With a cluster having nodes distributed geographically, your application performance would sink down because of GTM (XID/snapshot obtention, sequence value obtention) and network latency. This is the price to manage concurrency accurately. -- Michael |

By the way, is there any reason why you are *not* considering PostgreSQL as well? > 1) What is the minimum server requirement for this application ? There is no real *minimum* requirement AFAIK. However, coupling 1 Datanode and 1 Coordinator per server/VM could be useful to minimize network latency on queries. > 2) pgxc will be able to handle 500 concurrent calls on server ? Well yes, but a single Postgres server is able to handle that nicely as well if coupled with a connection pooler. I don't see much why multi-master is a requirement for such a low-number though as you seem to mean in your question. > 3) is there any parameter where i can define maximum connection ? max_connections on each Coordinator/Datanode * number of nodes. You could as well define different values of max_connections per node. > 4) If server crashes then i how to get data back. how to have back up > existing data ? This is a vast question, and without providing any details about what you are looking for in terms of backup and recovery strategy it is hard to guess anything but... This problem is similar to Postgres itself, except that in this case you need to manage N nodes and not 1. Just seeing your email and if you have a requirement with 500 concurrent connections, you might live happily with PostgreSQL + pgbouncer. Regards, -- Michael |

Hi All, I have very large application, as of now i am using MySQL but i want to convert it into postgre-xc. Queries: 1) What is the minimum server requirement for this application ? 2) pgxc will be able to handle 500 concurrent calls on server ? 3) is there any parameter where i can define maximum connection ? 4) If server crashes then i how to get data back. how to have back up existing data ? -- Thanks, Juned Khan iNextrix Technologies Pvt Ltd. www.inextrix.com |
