Hello,
I've had an issue recently in my Elasticsearch cluster of getting this error:
Trying to create too many scroll contexts. Must be less than or equal to: [500]
None of our _search
queries use that feature, but I have just discovered that _update_by_query
and _delete_by_query
do, with a default window of 5 minutes. There may be a bug in our code which results in them being called too frequently, but I was wondering if anybody knew of the danger of setting that to a low value (say 5 seconds?). Given that it doesn't return the scroll_id
, I assume the scroll context is only used for the duration of the _update
or _delete
?
Equally, is it valid to set it to 0s
? I tested it and it did perform the update, but I'm not sure if it just ignored the value?
