FTS, slow index after lots of deletes

Full Text Search
1

A bucket contains 300k objects, all small to medium size.
Some of those objets are FTS’ed, all of them are not dynamic.

at some point i needed to change my data model for one of the. types so i deleted it (simple DELETE from bucket where type = ‘X’). Delete wen OK but it takes a long time for FTS to delete those objects from it index.
The count of deleted objects is around 120k’.
Looking at the FTS UI i can see that the percentage is above 100% (my case it became 124%) and slowly, but really slowly getting down. For FTS to catch all the deletions elapsed more than 2 hours!

It’s CB v6, 3 nodes, search service got 5.5 GB ram and the cluster is not loaded at all (its our staging env).

Any advise?

Thanks

@shaike.marc,

This certainly looks like a weird situation that warrants deeper inspection.
Can you please create a support ticket with the cbcollected (logs) information from the cluster?

Cheers!

@sreeks,

Thanks for the quick response. It seems that it happens just on our STG env. When did that on prod, the indexers worked fluently.
