I’m extremely pleased to see that after months of efforts and contributions by different people around the world, Postgres-XL 9.5 R1 Beta1 has finally arrived. This release is significantly better, in all respects such as performance, stability and high availability, as compared to the past release. Enormous amount of work has gone into PostgreSQL in the […]
One of the problems with Postgres-XL 9.2 is that it assigns a global transaction identifier (GXID) for every transaction that is started in the cluster. Since its hard for the system to know if a transaction is read-only or not (remember, even SELECT queries can do write activities), Postgres-XL would always assign a GXID and send […]

In the previous blog post, I briefly explained how we got the performance numbers published in the pglogical announcement. In this blog post I’d like to discuss the performance limits of logical replication solutions in general, and also how they apply to pglogical. physical replication Firstly, let’s see how physical replication (built into PostgreSQL since […]
In Postgres-XL, sequences are maintained at the Global Transaction Manager (GTM) to ensure that they are assigned non-conflicting values when they are incremented from multiple nodes. This adds significant overhead for a query doing thousands of INSERTs in a table with a serial column, incrementing sequence one at a time and making a network roundtrip […]

Once we had a reasonably stable version of Postgres-XL 9.5, we shifted our attention to measure performance of this brand new version of Postgres-XL. Our choice of the benchmark […]
