> Support append-only indices in ES output
> -----------------------------------------
>
> Key: BEAM-12601
> URL: https://issues.apache.org/jira/browse/BEAM-12601
> Project: Beam
> Issue Type: Improvement
> Components: io-java-elasticsearch
> Reporter: Andres Rodriguez
> Assignee: Andres Rodriguez
> Priority: P2
> Fix For: 2.33.0
>
> Time Spent: 5h 10m
> Remaining Estimate: 0h
>
> Currently, the Apache Beam Elasticsearch sink is
> [using|https://github.com/apache/beam/blob/master/sdks/java/io/elasticsearch/src/main/java/org/apache/beam/sdk/io/elasticsearch/ElasticsearchIO.java#L1532]
> the
> [index|https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-bulk.html#bulk-api-request-body]
> bulk API operation to add data to the target index. When using append-only
> indices it is better to use the
> [create|https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-bulk.html#bulk-api-request-body]
> operation. This also applies to new append-only indexes, like [data
> streams|https://www.elastic.co/guide/en/elasticsearch/reference/7.x/use-a-data-stream.html#add-documents-to-a-data-stream].
> The scope of this improvement is to add a new boolean configuration option,
> {{append-only}}, to the Elasticsearch sink, with a default value of {{false}}
> (to keep the current behaivour) that when enabled makes it use the {{create}}
> operation instead of the {{index}} one when sending data.
