The default IndexDeletionPolicy just keeps the last commit only (KeepOnlyLastCommitDeletionPolicy) .Files belonging to older commits are removed. If the files are needed longer for replication, they are leased . The lease is extended 10 secs at a time. Once all the slaves have copied the lease is never extended and the files will be purged.
In the snapshot based system , unless the snapshots are deleted from the file system the old files will continue to live on the disk --Noble On Mon, Jan 5, 2009 at 6:59 PM, Mark Miller <markrmil...@gmail.com> wrote: > Noble Paul ??????? ?????? wrote: >> >> * SolrReplication does not create snapshots .
