Conference Schedule - PGConf.EU 2022
The curious case of the point of sales, and why we still need pglogical
When bad networks doesn't allow a client/server topology, some special solutions must be found. In this case we have a full PostgreSQL database in every point of sale and pglogical was used to replicate between the nodes.
This of course has it's own complications, in this talk we are going to show: - the original problem - how pglogical helped to manage the multiple origins problem - why native logical replication cannot be used here - what we need for native logical replication become a replace of pglogical
