RUM and WAL-generation
Hi all.
The RUM-index is very nice, but indexes get very large and produce insane amounts of WAL.
Due to the way PG works (IIUC), updating an int-column in a row produces lots of WAL because the whole row is duplicated, and if that row holds RUM-indexed columns it gets really bad...
We hav actually run out of WAL-space in production because of this.
I see this TODO-entry in RUM:
- Improve GENERIC WAL to support shift (PostgreSQL core changes).
What is the status on this?
