ConcurrentAppendException when using flyway on Databricks

[CarreauClement]

Hello,
When running our migration scripts with flyway on Databricks we often end up with the following error :

Message : Operation failed with error: [org.apache.hive.service.cli.HiveSQLException: Error running query: [DELTA_CONCURRENT_APPEND] io.delta.exceptions.ConcurrentAppendException: [DELTA_CONCURRENT_APPEND] ConcurrentAppendException: Files were added to the root of the table by a concurrent update. Please try the operation again.

Any idea why ?
Thanks

Hi @CarreauClement! Why would not you try to increase value of the setting flyway.lockRetryCount and set up flyway.group to true?
