Renaud Delbru updated SOLR-6460:
--------------------------------
    Attachment: SOLR-6460.patch

The latest version of the update log extension for cdcr. In addition of the 
previously described features, we extended the transaction log to compute and 
store the number of records in a tlog file. 
The patch SOLR-6819 is required for executing the unit tests.

> 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.
