It looks like the data is getting to the target servers. I see tlog files
with the right timestamps. Looking at the timestamps on the documents in
the collection none of the data appears to have been loaded.
In the solr.log I see lots of /cdcr messages action=LASTPROCESSEDVERSION,
action=COLLECTIONCHECKPOINT, and action=SHARDCHECKPOINT
no errors
autoCommit is set to 60000 I tried sending a commit explicitly no
difference. cdcr is uploading data, but no new data appears in the
collection.
