Understanding logical decoding and replication

Date: 2014-10-23
Time: 10:30–11:20
Room: Medici I
Level: Advanced

Logical decoding is a new plugin infrastructure added in PostgreSQL 9.4. With direct application for auditing, rolling upgrade and many more things, it makes possible decoding of WAL changes applied to a given database, user being afterwards able to give to those changes the shape he wants, applying or sending them following his will. This gives the user a full control of the replication flow and how it behaves in his cluster. The presentation deals with the basics of logical decoding, with a set of simple examples to help the listener apprehend this new infrastructure of 9.4, to be ready to develop his own features.
