Tim Robertson created BEAM-4389: ----------------------------------- Summary: Enable partial updates for Elasticsearch Key: BEAM-4389 URL: https://issues.apache.org/jira/browse/BEAM-4389 Project: Beam Issue Type: New Feature Components: io-java-elasticsearch Affects Versions: 2.4.0 Reporter: Tim Robertson Assignee: Tim Robertson
Expose a configuration option on the {{ElasticsearchIO}} to enable partial updates rather than full document inserts. Rationale: We have the case where different pipelines process different categories of information of the target entity (e.g. one for taxonomic processing, another for geospatial processing). A read and merge is not possible inside the batch call, meaning the only way to do it is through a join. The join approach is slow, and also stops the ability to run a single process in isolation (e.g. reprocess the geospatial component of all docs). Use of this configuration parameter has to be used in conjunction with controlling the document ID (possible since BEAM-3201) to make sense. The client API would include a {{withUsePartialUpdate(true)}} such as: {code} source.apply( ElasticsearchIO.write() .withConnectionConfiguration(connectionConfiguration) .withIdFn(new ExtractValueFn("id")) .withUsePartialUpdate(true) {code} -- This message was sent by Atlassian JIRA (v7.6.3#76005)
