Thread: db clustering?
I have some postgres cluster questions:
I would like to have the ability to dynamically re-size a cluster of Postgres DB instances.
0. Can I create a Postgres cluster?
- more than one instance of Postgres running on more than 1 cpu acting as a single instance of postgres to process work. i.e. 1 pg/cpu
1. start postgres on another box
2. have it added to the cluster and have it start processing work for it.
3. have the instance stop processing work and remove the instance from the cluster
Thanks

BOOK: Quite specific. It is, however, somewhat fuzzier on the subject of kneecaps.

There are pieces of software that, with the watchful eye of a competent dba can do most of what you ask, but there's no "push a button take a banana" interface / implementation.
