Hi All,
What are the different ways to tune query performance especially when accessing Databricks Delta Tables using reporting tools , example: Power BI
1) Partitions - ( Dynamic Partition Pruning)
2) Keeping cols 1 - 32 ( enable stats for data skipping)
3) Z Order columns -(frequently filtered and joined cols)
4) Optimize ( deal with small file issues)
5) Vacuum (cleanup files no longer needed)
I wanted understand if there are any other options left to tune performance other than increasing the compute/using photon especially for reporting needs.
Thanks,
Mohan
