----------------------------------
Summary: Is there any plan to support "date histogram aggregation"?
Key: CALCITE-4599
URL: https://issues.apache.org/jira/browse/CALCITE-4599
Project: Calcite
Issue Type: Improvement
Components: elasticsearch-adapter
Reporter: Jacky Yin
"date histogram aggregation" is one of the popular analysis function of elastic
search. It is not pushed down to elastic search in current calcite es adapter.
Is there any plan to support it? Given the below example, if it can be pushed
down to es, the query should be very efficient.
"select count(*) as cc from t group by date_histogram(`@timestamp`, interval
'5' minute)"
Another question is currently there seems no proper sql function/keyword for
date_histogram. One possible option is TUMBLE function. Is it right?
