Shivani Mall updated VXQUERY-168:
---------------------------------
Description:
Queries that have multiple let, for, where and return (FLOWR)
statements/expressions, tend to create very large queriy plans with nested
subplans. Because these are not optimized properly, these give the following
error: Attempting to construct a nested plan with 4 operator descriptors.
Currently, nested plans can only consist in linear pipelines of Asterix micro
operators.
