Approach to apply full index from master to slaves?

[William Bell <bi...@gmail.com>]

We have a 3GB index. We index on the master and then replicate to the
slaves.

But the issue is that after the slaves switch over - we get deadlocking, #
of threads increase to 500, and most times the SOLR instance just plain
locks up.

We tried adding a bunch of warming queries, but we still have a major
performance hit and same issues.

Are there any other tweaks and recommendations? Are others experiencing
this?

What's your max warming searcher value?

About warming queries, that may be _adding_ to your problem.
I'd first try removing many of them, especially if you have
your cache autowarm settings very high, try 16 or so.

Autowarming is all about pre-loading the caches etc, but you
reach diminishing returns pretty quickly.

And what are all the threads doing?
