[jira] [Commented] (SENTRY-874) Handle HMS updates correctly while full update is being built

    [ https://issues.apache.org/jira/browse/SENTRY-874?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15954198#comment-15954198 ] 

Alexander Kolbasov commented on SENTRY-874:
-------------------------------------------

We are changing the logic in sentry-ha-redesign branch for this.

The simplest approach we are taking now is to ensure that HMS doesn't change while we take an initial snapshot. We may try to do something fancier in the future.

> We have two options here:
> 1. Have a lock for path update + notify sentry. So that a partial update would just block until the full update completes building and notifying Sentry.
> 2. Make sure path update duplicates are handled well in HMSPaths and SentryPlugin
