--------------------------------------------------------------
A new patch that introduces efficient seeking over a list of transaction log
files. Efficient seeking is achieved by adding metadata (version number) to
tlog filename and by leveraging the filesystem's index. The tlog filename has
now the following syntax:
{noformat}
"tlog.${logId}.${startVersion}"
{noformat}

> 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.
