Subject [jira] Commented: (SOLR-561) Solr replication by Solr (for windows also)
Date Sun, 01 Jun 2008 09:36:45 GMT


Thomas Peuss commented on SOLR-561:

Thomas: This is something that can be considered. But , I am still not very convinced that
people use it that way. It is going to introduce some dependency on a new library. Let us
see if there is enough demand from users

The basic functionality is much more important of course (and much harder to do).

note :All the operations can be triggerred using http get. So a wget from cron can do the
trick in the current form

OK. Then ignore my comment. :-)

> 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
