TimescaleDB is an open-source time-series database optimized for fast ingest and complex queries. It is built on top of PostgreSQL, providing the reliability and robustness of PostgreSQL with additional features tailored for time-series data. TimescaleDB is widely used for monitoring, IoT, finance, and other applications that require efficient handling of time-series data.
One common issue that users may encounter is the error code TSDB-035, which indicates that the TimescaleDB background worker is not running. This can manifest as a lack of data ingestion or delayed processing of scheduled tasks, leading to performance degradation or data inconsistencies.
The error code TSDB-035 typically arises due to misconfiguration or resource constraints. The background worker is a critical component of TimescaleDB, responsible for executing continuous aggregates, compression, and other maintenance tasks. When it fails to run, these operations are disrupted.
postgresql.conf file.To resolve the TSDB-035 error, follow these steps:
Ensure that the TimescaleDB extension is correctly installed and configured. Check the postgresql.conf file for the following settings:
shared_preload_libraries = 'timescaledb'
Restart the PostgreSQL service after making changes:
sudo systemctl restart postgresql
Ensure that your system has adequate resources. Monitor CPU and memory usage using tools like top or htop. If resources are constrained, consider upgrading your hardware or optimizing other running services.
Examine PostgreSQL logs for any error messages related to TimescaleDB. Logs are typically located in /var/log/postgresql/. Look for entries that might indicate why the background worker is failing to start.
Ensure you are using the latest version of TimescaleDB, as updates often include bug fixes and performance improvements. Update TimescaleDB using:
sudo apt-get update
sudo apt-get install timescaledb-postgresql-12
Replace 12 with your PostgreSQL version.
By following these steps, you should be able to resolve the TSDB-035 error and ensure that the TimescaleDB background worker runs smoothly. For further assistance, refer to the official TimescaleDB documentation or seek help from the TimescaleDB community on Stack Overflow.
