Migrating Dockerized Zabbix PostgreSQL Backend to TimescaleDB
Recently, I had to migrate three zabbix instances to TimescaleDB for better performance as the databases kept growing, hence, I decided to write a blog on the procedure I took and challenges I faced. Zabbix’s reliance on a relational database for storing time-series metric data is a classic architectural challenge. As history and trend tables grow into the billions of rows, query performance inevitably degrades. The solution? Augmenting PostgreSQL with TimescaleDB. By leveraging hypertables for automatic partitioning and native compression, you can drastically improve data ingestion, query speed, and storage efficiency. In this post, we’ll detail the technical steps for a seamless migration from a vanilla PostgreSQL backend to TimescaleDB. ...
