-------------------------------
> Code improvements to the ElasticSearch connector

> Key: FLINK-7150
> URL: https://issues.apache.org/jira/browse/FLINK-7150
> Project: Flink
> Issue Type: Improvement
> Components: ElasticSearch Connector
> Affects Versions: 1.3.1
> Reporter: Stephan Ewen
> Assignee: Stephan Ewen
> Fix For: 1.4.0
>
>
> I suggest some improvements to the handling of generic types, inner classes,
> and serializability:
> - Remove Serializable from the {{RequestIndexer}}, because they are neither
> required to be serializable (they are created in open()) nor is the main
> implementation ({{BulkProcessorIndexer}}) actually serializable.
> - Make {{BulkFlushBackoffPolicy}} a static inner class, which avoids adding
> outer class during serialization and clears various warnings about raw
> reference to outer class
> - Fixe various raw generic type warnings for the use of {{ActionRequest}}
