Gaurav Shah commented on SPARK-9215: ------------------------------------ [~tdas] ping > Implement WAL-free Kinesis receiver that give at-least once guarantee > --------------------------------------------------------------------- > > Key: SPARK-9215 > URL: https://issues.apache.org/jira/browse/SPARK-9215 > Project: Spark > Issue Type: Improvement > Components: DStreams > Affects Versions: 1.4.1 > Reporter: Tathagata Das > Assignee: Tathagata Das > Fix For: 1.5.0 > > > Currently, the KinesisReceiver can loose some data in the case of certain > failures (receiver and driver failures). Using the write ahead logs can > mitigate some of the problem, but it is not ideal because WALs dont work with > S3 (eventually consistency, etc.) which is the most likely file system to be > used in the EC2 environment. Hence, we have to take a different approach to > improving reliability for Kinesis. > Detailed design doc - > https://docs.google.com/document/d/1k0dl270EnK7uExrsCE7jYw7PYx0YC935uBcxn3p0f58/edit?usp=sharing -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
