[jira] [Commented] (HBASE-15320) HBase connector for Kafka Connect

["Mike Wingert (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-15320?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16052915#comment-16052915 ] 

Mike Wingert commented on HBASE-15320:
--------------------------------------

First, thanks to the hbase-indexer folks for giving me the idea on how to make this work.

Comments on my patch:
- it starts up a barebones region server that just receives replication events
- it allows you to specify various rules to route the replication messages or drop them
- It takes each Cell and transforms it into a avro message before posting it to the kafka topic.

> Implement an HBase connector with source and sink tasks for the Connect framework (http://docs.confluent.io/2.0.0/connect/index.html) available in Kafka 0.9 and later.
> See also: http://www.confluent.io/blog/announcing-kafka-connect-building-large-scale-low-latency-data-pipelines
> An HBase source (http://docs.confluent.io/2.0.0/connect/devguide.html#task-example-source-task) could be implemented as a replication endpoint or WALObserver, publishing cluster wide change streams from the WAL to one or more topics, with configurable mapping and partitioning of table changes to topics.  
> An HBase sink task (http://docs.confluent.io/2.0.0/connect/devguide.html#sink-tasks) would persist, with optional transformation (JSON? Avro?, map fields to native schema?), Kafka SinkRecords into HBase tables.
