The state of in-core changeset extraction

Date: 2013-11-08
Time: 17:00 - 17:45
Room: Room 2
Level: Intermediate

Changeset extraction is the capability to get a stream of changes performed in a database - like INSERT, UPDATE, DELETE - in a convenient format to use in replication, auditing and lots of other usecases. We have worked on an implementation of that has a very low storage and cpu overhead by virtue of reusing the already existing write ahead log. The patch for that has good chance to get committed to 9.4 (to-be-released in the summer of 2014).

This talk will explain the architecture of changeset extraction and include a demo of what it can be used for.
