[jira] [Comment Edited] (SENTRY-2396) Minimize the time sentry blocks HMS threads

    [ https://issues.apache.org/jira/browse/SENTRY-2396?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16609235#comment-16609235 ]

--------------------------------------------------------------------------

[~LinaAtAustin] Conceptually SENTRY-2300 will address the 0.5.sec delay in fetching the notifications but this approach significantly changes the current way of fetching changes to HMS data and the changes are not trivial.  We need to look very closely to understand all the effects of doing so.

 

[~akolb] I have plans to address the delay in the Follower node in another Jira[SENTRY-2397]. Idea is to increase the frequency of the polls in the Follower when it's not in leader.

> Currently HMS is blocked for max of one sec by sentry for below operations
>  # create database
>  # drop database
>  # create table
>  # drop table
>  # alter table
> Reason for this is to make sure that sentry fetched  the notification event from HMS and processed.
