>                 URL: https://issues.apache.org/jira/browse/FLINK-4491
>             Project: Flink
>          Issue Type: Improvement
>          Components: Streaming Connectors
>    Affects Versions: 1.1.0
>            Reporter: Flavio Pompermaier
>            Priority: Minor
>              Labels: elasticsearch, streaming
>
> At the moment is not possible to configure the number of shards if an index 
> does not already exists on the Elasticsearch cluster. It could be a great 
> improvement to handle the index.number_of_shards (passed in the configuration 
> object). E.g.:
> {code:java}
> Map<String, String> config = Maps.newHashMap();
> config.put("bulk.flush.max.actions", "1");
> config.put("cluster.name", "my-cluster-name");
> config.put("index.number_of_shards", "1");
> {code}
