Hi,

Yes, we have a plan. But it will take some time to bring this to presto
integration as we need to first bring up and stabilize the MV module and
also need to analyze how to update the query plan to use pre-agg tables in
presto .

Regards,
Ravindra.

Hi xm_zzc

Good questions.
As you know, pre-aggregate table use the datamap, need to change query plan,
it will be considered after 1.5.2.

Before presto integration is alpha feature, 1.5.2 will do pretty
optimizations and change presto integration to formal feature(support to
deploy in production).

Regards
Liang
