Subject [jira] [Commented] (FLINK-10042) Extract snapshot algorithms from inner classes into full classes
Date Tue, 14 Aug 2018 19:01:00 GMT

    [ https://issues.apache.org/jira/browse/FLINK-10042?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16580283#comment-16580283

ASF GitHub Bot commented on FLINK-10042:

StefanRRichter opened a new pull request #6556: FLINK-10042][state] Extract snapshot algorithms
from inner classes of RocksDBKeyedStateBackend into full classes
URL: https://github.com/apache/flink/pull/6556
   ## What is the purpose of the change
   This PR is part 2 in the refactoring/decomposition of `RocksDBKeyedStateBackend`. All snapshotting
algorithms are extracted from the backend file into their own full classes.
   In a second step, the PR also introduces `AsyncSnapshotCallable` as a general strategy
for asynchronous snapshots that outlines resource de/allocation, closing, and cancellation.
   ## Verifying this change
   This change is already covered by existing tests, and I added `AsyncSnapshotCallableTest`.
   ## Does this pull request potentially affect one of the following parts:
     - Dependencies (does it add or upgrade a dependency): (no)
     - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: (no)
     - The serializers: (no)
     - The runtime per-record code paths (performance sensitive): (no)
     - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing,
Yarn/Mesos, ZooKeeper: (yes)
     - The S3 file system connector: (no)
   ## Documentation
     - Does this pull request introduce a new feature? (no)
     - If yes, how is the feature documented? (not applicable)
