Renaud Delbru updated SOLR-6460:
--------------------------------
Attachment: SOLR-6460.patch
Here is a first patch with an initial implementation of the CdcrUpdateLog which
includes:
* a cleaning of the old logs based on log pointers
* a log reader that reads both the old and new tlog files.
Many nocommit or todos, but this might provide enough materials for discussion.
> Keep transaction logs around longer

> Transaction logs are currently deleted relatively quickly... but we need to
> keep them around much longer to be used as a source for cross-datacenter
> recovery. This will also be useful in the future for enabling peer-sync to
> use more historical updates before falling back to replication.
