Hello,
I would like some details on the autocommit mechanism. I tried to search
the wiki, but found only the
standard maxDoc/time settings.
i have set the autocommit parameters in solrconfig.xml to 8000 docs and
300000milis.
Indexing at around 200 docs per second (from multiple processes, using
the CommonsHttpSolrServer class),
i would have expected autocommits to occur around every 40 seconds,
however the jvm log shows the following - sometimes more than two calls
per second:
$ tail -f jvm-default.log | grep "commit"

additionally, in the solr admin page , the update handler reports as
many autocommits as commits -
so i assume it is not some commit(); line lost in my code.
I actually get the feeling that the commits are triggered more and more
often - with not-so-nice
influence on indexing speed over time. Restarting resin seems to get the
commit rate to the original level.
Optimizing has no effect.
Is there some other parameter influencing autocommit?
Thank you very much.
