As far as I can see from Async search | Elasticsearch Reference [7.11] | Elastic - the default keep-alive value for async search is 5 days and is regulated on the query side.
This results in .async_search index on our CCS nodes growing to unreasonable size.
Is it possible to change the default value of the
keep_alive parameter for async searches, so the .async_search index does not grow in size that much?
I would say that 1 minute is more than enough for all our use-cases.
