Noble Paul commented on SOLR-561:
---------------------------------
Thanks.
I guess Lucene must be cleaning it up because that is what the
deletion policy says
Good point. Will incorporate that
Because the file names are unique it did not matter if I used the
index version (or does it) . Please clarify
Yeah . It does that . If all the files are not copied completely it aborts.
You are right. When the replication process starts , a lock is
acquired. The lock is released only after the process completes

> Project: Solr
> Issue Type: New Feature
> Components: replication
> Affects Versions: 1.3
> Environment: All
> Reporter: Noble Paul

> The current replication strategy in solr involves shell scripts . The
> following are the drawbacks with the approach
> * It does not work with windows
> * Replication works as a separate piece not integrated with solr.
> * Cannot control replication from solr admin/JMX
> * Each operation requires manual telnet to the host
> Doing the replication in java has the following advantages
> * Platform independence
> * Manual steps can be completely eliminated. Everything can be driven from
> solrconfig.xml .
> ** Adding the url of the master in the slaves should be good enough to enable
> replication. Other things like frequency of
> snapshoot/snappull can also be configured . All other information can be
> automatically obtained.
> * Start/stop can be triggered from solr/admin or JMX
> * Can get the status/progress while replication is going on. It can also
> abort an ongoing replication
> * No need to have a login into the machine
> This issue can track the implementation of solr replication in java
