ERR_H2_DB_TOO_BIG_TO_BE_CLEANED: Very large database

Your instance of Dataiku DSS uses H2 for its runtime databases. When the H2 database files become too large, cleaning the internal database using the Clear internal databases macro can lead Dataiku DSS to become unresponsive for several hours or days.

Remediation

See these instructions to learn how to migrate to PostgreSQL database or contact support. If you accept the consequences of cleaning a very large H2 internal database, you can use the Bypass database size checks parameter of the Clear internal databases macro.
