> Add support for columnar event serializer in HDFS
> -------------------------------------------------
>
> Key: FLUME-1669
> URL: https://issues.apache.org/jira/browse/FLUME-1669
> Project: Flume
> Issue Type: New Feature
> Components: Sinks+Sources
> Reporter: Mubarak Seyed
> Assignee: Mubarak Seyed
> Labels: noob
> Fix For: v1.4.0
>
>
> Motivation:
> Columnar storage is preferred for better performance and compression for
> low-latency analytical workloads. Avro 1.7.2 supports column-major file
> format [1]
> and we can implement {{AbstractTrevniAvroEventSerializer}} (as like
> {{AbstractAvroEventSerializer}}). {{HDFSSink}} can have serializer type to
> store events in Trevni column-major file format.
