Обсуждение: replication solution
Hi all, we are looking for a solution to create a replicated database to be used as reporting database with same data of production ( we can accept a lag of some minutes). we already have the Point In Time Recovery but we need a solution where the standby is always open in readonly , but the data is replicated continuosly from primary. The Slony solution could be a possibility but the production database is 80 Gb of data with around 10000 transaction each hour. DO you have some suggestion for our implementaiont if exists?? thanks a lot Silvio --- Utilizziamo i dati personali che la riguardano esclusivamente per nostre finalità amministrative e contabili, anche quandoli comunichiamo a terzi.

What's your time frame? The Hot Standby and Streaming Replication features in PostgreSQL 9.0 will do exactly that. 9.0 is currently in beta testing and expected to be released next month. These new features are based on PITR techniques, but SR allows the WAL data to flow across a connection in near real-time, and HS allows the standby to be used for read-only queries. -Kevin

We do at least 15x more transactions with Slony, w/o any issues. Slony should be good for you. -- Devrim GÜNDÜZ PostgreSQL DBA @ Akinon/Markafoni, Red Hat Certified Engineer devrim~gunduz.org, devrim~PostgreSQL.org, devrim.gunduz~linux.org.tr http://www.gunduz.org Twitter: http://twitter.com/devrimgunduz

Slony (or Londiste) can handle that without issue, at all. Joshua D.

Bucardo, too. All three work on similar principles. rls -- :wq

PostgreSQL 9.0 is production ready now and supports Hot Standby, which is exactly what you want. -- Simon Riggs www.2ndQuadrant.com PostgreSQL Development, 24x7 Support, Training and Services
I've heard that rubyrep (http://www.rubyrep.org) is a good tool for replication too. I think it has gained popularity because of its ease of use. On a similar note I am eager to try postgreSQl 9.0 bulit in hot standby solution.I can't really wait till Postgersql rolls out replicated solution which can also be used for a failover.
