Noble Paul commented on SOLR-561:
---------------------------------
bq.I usually replicate on optimize only but I wonder if people use the current
ability to replicate on commit and on optimize. It doesn't seem to be possible
with your current patch.
technically it is possible just add two entries for _replicateAfter_. The code
is not handling it because _NamedList_ did not have a _getAll()_ method at that
time. The next patch will take care of it
> Solr replication by Solr (for windows also)

> 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
