When we use it for prometheus remote read, we met an issue that if we query data in a period long ago, it will cost such a long time to get the result.
Through the log, we found out that the query condition is as below:
"date >= toDate(1574999700) AND ts >= toDateTime(1574999700) and ts <= toDateTime(1575021600)"
But since the table should be partitioned by date, so, such query condition will seach all records from the start point till now.
So I made this change to make the query condition as below to guarantee clickhouse just search records in the specified range:
"date >= toDate(1574999700) AND ts >= toDateTime(1574999700) and ts <= toDateTime(1575021600) and date<=toDate(1575021600)"
