Hi Dremio Team,
we are running some complex query in dremio and based on query profile most of the time is spent in expression evaluation.
total execution time: ~5 mins
gandiva expression evalation: ~4 mins (with 8 executors. each thread gandiva evaluation time is in 6 digits)
Are there any ways to improve the performance for these kind of queries?
dremio version: 4.1.3 CE
Query profile:
