             Summary: Sql. Decouple ExpressionExecution part from 
ExecutionContext
                 Key: IGNITE-26635
                 URL: https://issues.apache.org/jira/browse/IGNITE-26635
             Project: Ignite
          Issue Type: Improvement
          Components: sql ai3
            Reporter: Konstantin Orlov


As for now, every sql expression interface requires {{ExecutionContext}} as 
input. The problem is that {{ExecutionContext}} contains not only context 
required for expression evaluation, but also a lot of sql-related stuff like 
fragment information, executor, expression factory, etc. To simplify decoupling 
of expression execution engine, we should derive minimal context required for 
expression execution.
