Maksim Zhuravkov updated IGNITE-21279:
--------------------------------------
Description:
Given partition pruning information for each scan operator of a QueryPlan, we
can evaluate a partition pruning predicate against statement's execution
context to prune partitions that scan operations won't touch.
1. Use affinity function and statement's execution context to evaluate
partition pruning predicates for each scan operator, so enlist is only called
for partitions that should be scanned.
2. Support table scans, system view scans, and index scans.
After this issue is resolved, partition pruning should work for SELECT queries.

Given partition pruning information for each scan operator of a QueryPlan, we
can evaluate a partition pruning predicate
against current execution context to prune partitions that scan operations
won't touch.
1. Use affinity function and statement's execution context to evaluate
partition pruning predicates for each scan operator, so enlist is only called
for partitions that should be scanned.
2. Support table scans, system view scans, and index scans.
