Maryann Xue updated PHOENIX-2198:
---------------------------------
Attachment: PHOENIX-2198.patch
1. Added RuntimeContext/RuntimeContextImpl for setting and getting correlate
variables.
2. Added CorrelateVariableFieldAccessExpression which will be evaluated at
runtime and serialized to server (if necessary) as LiteralExpression.
3. Added CorrelatedPlan and CorrelatedPlanTest.
4. Added dynamicFilter to BaseQueryPlan. The compiler will be responsible for
testing if the filter expression contains any
CorrelateVariableFieldAccessExpression and if this "dynamic part" will have
impact on ScanRanges. This dynamic filter should be set when both conditions
return true. (This part is in calcite branch.)
5. Made minor changes to HashJoinPlan and UngroupedAggregatingResultIterator.
