arjansh commented on issue #229: Upgrade to Elasticsearch 7.3.1 URL: https://github.com/apache/metamodel/pull/229#issuecomment-543535205 When doing lots of updates (more than 500) in a short period of time (less than 60 seconds), Elasticsearch will fail with this message: "Trying to create too many scroll contexts. Must be less than or equal to: [500]". This is caused by the fact that in the DeleteAndInsertBuilder#getRowsToUpdate() method a DataSet is created, which is converted to a List of rows, which is returned by the method, but the DataSet isn't closed, as a result of which, in case of Elasticsearch, the scroll request for the DataSet isn't cleared and will stay alive for 60 seconds. I want to address this problem within this pull request.
