Though "replication" is a single term, there are two major replication |
|
|
|
|
technologies. Multi-master replication allows read/write queries to be |
|
|
|
|
sent to multiple replicated computers. This capability has a serious |
|
|
|
|
performance impact. Pgcluster is the most popular such solution |
|
|
|
|
available for PostgreSQL. Master-slave replication allows a single |
|
|
|
|
master to receive read/write queries, with slaves able to accept only |
|
|
|
|
read/SELECT queries. The most popular master-slave PostgreSQL |
|
|
|
|
replication solution is Slony. There are also commercial and |
|
|
|
|
hardware-based replication solutions available. |
