HDDS-1802. Add Eviction policy for table cache. by bharatviswa504 · Pull Request #1100 · apache/hadoop

bharatviswa504 · 2019-07-16T00:24:09Z

bharatviswa504 · 2019-07-16T00:35:38Z

One missing thing in this PR is on the restart, we should load up tables with cache, where cleanup policy is NEVER from DB. Will post a fix for that in next commit.

arp7 · 2019-07-16T00:59:40Z

hadoop-hdds/common/src/main/java/org/apache/hadoop/utils/db/TypedTable.java

I understand why we added this policy-specific check here. However it is probably misplaced here. Your original solution to have two cache types with isExist overloaded was probably better.

arp7 · 2019-07-16T01:00:17Z

hadoop-hdds/common/src/main/java/org/apache/hadoop/utils/db/TypedTable.java

Same here.. we should not have these checks here.

arp7 · 2019-07-16T01:01:32Z

hadoop-hdds/common/src/main/java/org/apache/hadoop/utils/db/cache/TableCacheImpl.java

The Cache doesn't know it is being invoked on flush.. so this check is misleading.

It is caller responsibility to call this method after the flush. And right now this is called only after flushing to DB from OzoneManagerDoubleBuffer.

So, if it is NEVER, we will not do the cleanup.

arp7 · 2019-07-16T20:15:43Z

Capturing our offline discussion. We discussed the following:

Populate full cache on process startup (mentioned by Bharat).
Move decision for full lookup into cache implementation. The result will be communicated to TypedTable.
Rename AFTER_FLUSH to MANUAL.

Anything I missed?

Thank You @arp7 for the offline discussion.
And one more comment by you, when delete of cache entry (like delete volume/bucket), we should delete cache entry, as for full cache, cleanup will not happen.
