Hi Team,

I'm attempting to retrieve a large collection of data and apply filtering based on datetime, but the performance is quite slow. Despite adding a datetime filter index to the MongoDB collection, it seems that the index is not being utilized by drill.

Please find the sample query which i am executing from apache drill

select * FROM mongo.sampletable WHERE SentTime >= TO_TIMESTAMP('2023-08-10 00:00:00', 'yyyy-MM-dd HH:mm:ss') AND SentTime < TO_TIMESTAMP('2023-08-17 00:00:00', 'yyyy-MM-dd HH:mm:ss') LIMIT 10

any leads will be apricated.

Thanks

Can you attach the query profile here? In the Drill web UI, Profiles -> (your query) -> JSON profile.
