HSQL (file-based) database considerations

Please note we do not recommend using the HSQL (file-based) database for deploys over 100 devices, and do not support HSQL deploys with 1000+ devices.

Since HSQL is a file based database, that keeps all data in a few flat text-based files, as the DB size grows, performance is severely impacted. If you want to use HSQL long-term, you should:

• setup data retention policies for both History Jobs and Backups (in "Other Settings")
• monitor database directory size (it should not reach multi-gigabyte sizes)
• monitor disk usage of the disk where HSQL stores its data

HSQL databases can get corrupted if the disk on which data is stored runs out of space.
