Webster Homer commented on SOLR-11724:
--------------------------------------
We are seeing this behavior in 7.2.0. Sometimes the data shows up in a search,
but when I look there are no index segments. It appears to be searching just
tlogs.
This looks like a critical issue to me.
We observed the same behavior when we deleted all the data from a collection.
On;y tlogs show up and only half are searchable. The configuration worked with
Solr 6.1 but doesn't with Solr 7.2. We don't see any errors. We see logs of
calls to /cdcr LASTPROCESSEDVERSION in the logs
We don't just see this as a bootstrap issue either, we only see about half the
data get replicated. I don't know if tlogs are present on the targets, as I
don't have access to those file systems
> Cdcr Bootstrapping does not cause "index copying" to follower nodes on Target

> http://lucene.472066.n3.nabble.com/Issue-with-CDCR-bootstrapping-in-Solr-7-1-td4365258.html
> 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.
