In a previous blog post we talked about the technical details behind the new CassandraFDW that enables PostgreSQL to connect to a Cassandra cluster. This provides PostgreSQL users the ability to easily read and write data to a very popular open source multi-master database that can support writes in multiple data centers. This means if [...]
In any modern PostgreSQL installation, there's usually at least one streaming replication standby server feeding off your production master. In fact, there's usually several. Being the good PostgreSQL administrator that you are, you've already enabled logging of replication commands in postgresql.conf thusly: log_replication_commands = on But what you're probably not doing is having each standby [...]
Finding performance problems in deeply nested PL/pgSQL business logic is difficult.One of the reasons is that PL/pgSQL hides anything happening in the PL code. None of the SQL queries inside of all the nested function and trigger calls ever shows up in...
In the previous post, we provided a business and architectural background for the Postgres FDWs that we are developing for Spark, Hadoop and Cassandra. In particular, we highlighted the key benefits of bringing Cassandra and PostgreSQL together. With this post, we will start taking a more technical look at the Cassandra FDW. The C* FDW [...]

I wanted to test it out with the PostgreSQL sandbox from the BigSQL project. Setting up PostgreSQL Sandbox and Installing pgBackRest The BigSQL [...]
