Is there a limit to the number of indexes an ElasticSearch alias can point to?

Elastic Stack Elasticsearch
#1

I have this alias that I want to point to 60 indexes. At 21 indexes, I
start getting Execution Rejected exceptions.

Is this because of a 20 index limit in the alias API?

Any help would be much appreciated,
Jieren

Hi,

there's no such hard limit -- see the demo in
Ruby: http://beta.pastie.org/5436199. Maybe you're hitting some other limit
(open connections, etc) -- please post more info.

It's generally considered a better pratice to not cross-post between
StackOverflow [1] and the mailing list, since it's harder for people
interested in your problem to follow multiple channels.

Hi,

You may have hit the max size of some thread pool. Compare what you have
in the elasticsearch.yml and what stats API gives you.
