-------------------------------------
[~WebHomer],
Can you elaborate you cluster details, number of shards, number of replicas. I
am not able to comprehend the above statement of half data being searchable. If
something use to work for 6.1 and not working for 7.2 is a concern. If the
replicators are started successfully (CDCR=START), there is no reason
whatsoever the data won't get replicated to target to either shards and won't
be searchable after commit.
Here, if not a single document is indexed in source after bootstrapping done on
target. The replicas of the target collections which are non-leader will have
empty index. To ignore this issue, having 1 replica each on target is the
immediate fix, as one will not see empty indexes on either cores, let me know
if the above doesn't make sense.
> Cdcr Bootstrapping does not cause "index copying" to follower nodes on Target

> If we index significant documents in to Source, stop indexing and then start
> CDCR; bootstrapping only copies the index to leader node of shards of the
> collection, and followers never receive the documents / index until and
> unless atleast one document is inserted again on source; which propels to
> target and target collection trigger index replication to followers.
> This behavior needs to be addressed in proper manner, either at target
> collection or while bootstrapping.
