Queries

I was recently setting up a demo to show off query logging features. Two common extensions, pg_stat_statements and pg_stat_monitor, store data locally. In the case of a distributed database, it is helpful to combine the query runtimes on all nodes.

YugabyteDB supports foreign data wrappers, so I decided to use this feature to combine query statistics from each of my three test nodes.

The libraries for the pg_stat_monitor extension are already installed, so the extension just needs to be created:

I made slight changes to the Debezium UI example for local demo purposes, here:

Here’s a brief screen recording of how to configure the Debezium postgres connector in the UI using the values from the docker-compose setup.

Quick post to share my presentation last week at the YugabyteDB Friday Tech Talk. It was on fuzzy matching, and more generally string searches. Got to nerd out on two of my favorite topics: words (broadly, linguistics and specifically, names) and databases. Check it out!
