[jira] [Commented] (SENTRY-2396) Minimize the time sentry blocks HMS

    [ https://issues.apache.org/jira/browse/SENTRY-2396?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16607482#comment-16607482 ] 

kalyan kumar kalvagadda commented on SENTRY-2396:
-------------------------------------------------

Sentry server currently fetches events from HMS periodically causing HMS threads to be blocked. This can be minimized by fetching the notification event from HMS immediately when sentry knows that HMS will be blocked.

 

*Advantage:* HMS is not blocked.

*Disadvantage:* There will be more fetch requests from sentry towards HMS.

> Currently HMS is blocked for max of one sec by sentry for below operations

>  # alter table
> Reason for this is to make sure that sentry fetched  the notification event from HMS and processed.
