Hi All,

 

We are using a shared datastore for author and publishers in our platform.

As we are currently facing the reference files are creating in s3 under meta folder which is causing take huge memory.

 

When we run the garbage collection for boolean value as a false then i am seeing some of the bold ids are missing and when i try to search those specific id's in our s3 datastore in s3 am unable to find.

 

Could you please let me know if any once has encounter the same issues?

 

Thanks,.

#Maximum size of a segment in MB. The default maximum is 256MB.
#tarmk.size=256

#Boolean value indicating that a custom data store is used. The default value is false.
customBlobStore=B"true"

#pauseCompaction=B"true"

#Determines if this Node Store should be started in standby mode.
standby=B"false"

blobTrackSnapshotIntervalInSecs=L"0"

    Hi @santhoshm687661 

    If the datastore is shared between repositories, we need to 

    • run the GC with markOnly as true in all the instances (mark)
    • Then run with markOnly as false in one of the instances (sweep)

    Detailed explanation from official docs :
