Assignee: (was: Na Li)
> Performance Issue: Saving MAuthzPathsMapping should be done in batch for path
> full snapshot
> -------------------------------------------------------------------------------------------

> Key: SENTRY-2185
> URL: https://issues.apache.org/jira/browse/SENTRY-2185
> Project: Sentry
> Issue Type: Bug
> Components: Sentry
> Affects Versions: 2.1.0
> Reporter: Na Li
> Priority: Major
>
> From the code below, for each MAuthzPathsMapping, there is a query to save
> each MAuthzPathsMapping instance. Need to save the changes in batch.
> {code:java}
> public void persistFullPathsImage(final Map<String, Collection<String>>
> authzPaths,
> final long notificationID) throws Exception {
> tm.executeTransactionWithRetry(
> pm -> {
> pm.setDetachAllOnCommit(false); // No need to detach objects
> deleteNotificationsSince(pm, notificationID + 1);
> // persist the notidicationID
> pm.makePersistent(new MSentryHmsNotification(notificationID));
> // persist the full snapshot
> long snapshotID = getCurrentAuthzPathsSnapshotID(pm);
> long nextSnapshotID = snapshotID + 1;
> pm.makePersistent(new MAuthzPathsSnapshotId(nextSnapshotID));
> LOGGER.info("Attempting to commit new HMS snapshot with ID =
> {}", nextSnapshotID);
> for (Map.Entry<String, Collection<String>> authzPath :
> authzPaths.entrySet()) {
> pm.makePersistent(new MAuthzPathsMapping(nextSnapshotID,
> authzPath.getKey(), authzPath.getValue()));
> }
> return null;
> });
> }{code}
