I suspect concurrently updating and deleting the same document by query might cause this. (I can't give more then that) But still the problem exists. In the context of just picking up an online mapping change, documents which have been updated during the process, and therefore have a version conflict, would have picked up the new mapping anyway. current document has seqNo [4427] and primary term [2]] Then I have given a delay of 1 second between each update. Now Elasticsearch gets two identical copies of the above request to update the document, which it happily does. Repeat from 1) when in need. Sets the doc source of the update . 商品并发修改示图.

I want to get list of all (not only one bulk) ids of conflicted documents (for manual retry) or set up retry_on_conflict for update by query. Performance: remove the synchronous persistence mechanism from batch ElasticSearch DAO. The operation gets the document (collocated with the shard) from the index, runs the script (with optional script language and parameters), and index back the result (also allows to delete, or ignore the operation). Because the current enhanced persistent session mechanism, don't require the data queryable immediately after the insert and update anymore. /**Helper method to remove fields from source.

Restore from the 5.6.9 snapshot taken in the previous step into a new temporary index. The update() helper method allows you to add multiple update actions. Releasables.close(searcher); throw new VersionConflictEngineException(shardId, get.type(), get.id(), Update-mapping - How to solve related issues. Update a TTL mapping for an existing type; Remove a property from an existing mapping; Delete an existing mapping; Dynamic templates for attributes; Dynamic templates for indices; Mappings are the way you can define some sort of schema for a document type that will live in a given index.
