Hi Team,

We have a Server 2019, includes SQL Server 2019 with 4 instances, in one instance C:\Program Files\Microsoft SQL Server\MSSQL15.SGSFAROOJ\MSSQL\Log\Polybase\dump have 500GB size. We are not using Polybase services. So if we delete those logs, any issues will occurs. Kindly advise and check attached image.

    Hi @Shabin Suresh

    You can refer to the discussion in this thread: https://learn.microsoft.com/en-us/answers/questions/334078/polybase-issue-about-continuous-producing-of-dump.

    The answers to this thread include stopping the Poly database service through the SQL configuration tool to resolve this issue. But as Erland said, a better solution is to apply the latest cumulative update.

    You can delete those files without issue.

    These files are the result of a known issue with the release version of SQL 2019. Make sure that you have the most recent Cumulative Update installed, so that you don't get new dump files.

    If you have Polybase installed without using it, you may be inclined to uninstall it, but I cannot really recommend that. That is, I tried removing Polybase from my SQL 2019 instance, but this failed.
