Does elasticsearch invalidate aggregation cache every single doc update ? Our indexer service run all day long in every 5 mins and tracks the data in relational database and updates changed docs in ElasticSearch. If on every update Elasticsearch invalidates cache, the cache mechanism on elasticsearch doesnt seem to work for us. We could change indexer service times by this case true or false. ---

It invalidates it when a segment is changed, ie a new/deleted doc or a merge. ---

Thanks @warkolm. We need to increase update times then. ---
