Do you have components that only change different parts of the documents (one is updating facebook info, the other twitter) and each different updater can only run at once, then you can use a small number (the number of updaters plus some legroom). (say src.ip and dst.ip). External versioning (version types external & external_gte) is not supported by the update API as it would result in Elasticsearch version numbers being out of sync with the external system. What happens when the two versions update different fields? Instead of acquiring a lock every time, you tell Elasticsearch what version of the document you expect to find. must have the, To make the result of a bulk operation visible to search using the, Automatic data stream creation requires a matching index template with data Note that Elasticsearch does not actually do in-place updates under the hood. My understanding is that the second update_by_query should not ever fail with "version_conflict_engine_exception", but sometimes I see it continue to fail over and over again, reliably. Each newline character may be preceded by a carriage return \r. (Optional, string) Maybe one of the options has changed? See. The parameter is only returned for failed operations. If the list contains duplicates of the tag, this There is no "correct" number of actions to perform in a single bulk request. To illustrate the situation, let's assume we have a website which people use to rate t-shirt design. Discuss the Elastic Stack shards on other nodes, only action_meta_data is parsed on the We will soon run out resources if people repeatedly index documents and then delete them. Whether or not to use the versioning / Optimistic Concurrency Control, depends on the application. @clintongormley But single client and single Elasticsearch node has been used and client sent both requests in range of single connection(http 1.1 with keep-alived connection).
