Index corrupted detection from http get command.

[Michel Dion <di...@gmail.com>]

Hello,

I'm look for a way to detect solr index corruption using a http get
command. I've look at the /admin/ping and /admin/luke request handlers but
not sure if the their status provide guarantees that everything is all
right. The idea is to be able to tell a load balancer to put a given solr
instance out of rotation if its index is  corrupted.

Thanks

Michel

There's no way to do this that I know of..... There's the checkindex
tool, but it's fairly expensive resource-wise and there's no HTTP
command to do it.

We are going to production in a couple of weeks and up to now we haven't
experiment any index corruption during our development. I was asking that
because our SLA requires high availability and I want to make sure that we
can react quickly if corruption occurs. I think I'll go ahead with a
/admin/ping periodically called from the load balancer. Should be ok.

Thanks.

Would a non-successful /select?q={!cache=false}*:* query be sufficient?  (if so, /admin/ping would do the trick)  What's causing index corruption in your environment?  That's a very unusual occurrence that would be good to have identified in gory detail if you can.
