--------------------------------------

[~vitalii] can you add a comment about our discussion this morning? As I 
understand, the fix requires that we upgrade to Calcite 1.16.

> Support transitive closure during filter push down and partition pruning

> There is Calcite rule JoinPushTransitivePredicatesRule but it does not work 
> in Drill. 
> Applying it in Drill will allow for equi-join queries to push filter 
> condition from one table to another:
> {code:sql}
> select * 
> from A, B 
> where
> A.id = B.id and 
> B.id = 100
> {code}
> In that case it is possible that Scan operator for A table will not scan all 
> data. 
> For table A it can lead for applying: 
> 1. [Partition pruning for Hive or file system Parquet 
> tables|https://drill.apache.org/docs/partition-pruning-introduction/] 
> 2. [Parquet filter 
> pushdown|https://drill.apache.org/docs/parquet-filter-pushdown/]
