pengfei.zhan commented on KYLIN-5784:
-------------------------------------
h1. Root Cause
The old design was to get the engine type and model information from the query
history and then display the query history associated with it based on the name
filter. This is very inefficient because the query history table is scanned
across the entire table.
h1. Design
To filter the query history related to all models from current project
directly, rather than get these models from the query history.
> Optimization for query history filters
