Hi, I have memory problems with aggregation queries. my elastic version is 1.3.2 I tired to define \_timestamp as doc value , but when I checked the mapping I can see it didn't work It didn't happen in other fields. Is there any known issue with timestamp field and doc values? Lib -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

This is indeed a bug, I opened [Mappings: \_timestamp does not serialize its doc\_values settings · Issue #8893 · elastic/elasticsearch · GitHub](https://github.com/elasticsearch/elasticsearch/issues/8893). Thanks for reporting it!
