replication solution

am 24.08.2010 15:46:08 von Silvio Brandani

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

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.

We do at least 15x more transactions with Slony, w/o any issues. Slony=20=
=20
should be good for you.

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