cdcr replication of new collection doesn't replicate

[Webster Homer <we...@sial.com>]

We have just upgraded our QA solr clouds to 7.2.0
We have 3 solr clouds. collections in the first cloud replicate to the
other 2

For existing collections which we upgraded in place using the lucene index
upgrade tool seem to behave correctly data written to collections in the
first environment replicates to the other 2

We created a new collection has 2 shards each with 2 replicas. The new
collection uses tlog replicas instead of NRT replicas.

We configured CDCR similarly to other collections so that writes to the
first are sent to the other 2 clouds. However, we never see data appear in
the target collections.
We do see tlog files appear, and I can see cdcr update messages in the
logs, but none of the cores ever get any data in them. So the tlogs
accumulate but are never loaded into the target collections

This doesn't seem correct.

I'm at a loss as to what to do next. We will probably copy the index files
from the one collection to the other two collections directly, but
shouldn't cdcr be sending the data?

Does cdcr work with tlog replicas?

Re: cdcr replication of new collection doesn't replicate

It looks like CDCR is entirely broken in 7.2.0
We have been using CDCR to replicate data from our on Prem systems to
solrclouds hosted in Google Cloud.
We used the lucene index upgrade to do an in place upgrade of the indexes
in all our systems
In at least one case we deleted all the rows from a collection. The delete
did propagate to the clouds

Then we loaded data into that collection. Only half the data is available
in the search. Using the Solr console I see that the index segments show no
data. All of the search results are from tlog files

The only time CDCR has been reliable has been the delete. Otherwise it
doesn't seem to work very well.
