[ASTERIXDB-3299][COMP] Out of memory during query compilation
- user model changes: no
- storage format changes: no
- interface changes: yes
Details:
In case of deeply nested object or list is used in an upsert
statement or query, the compilation either fails with out of
memory error or takes a long time to complete. The issue is
with the recursive calls to getSerializerDeserializer in
ARecordSerializerDeserializer, AOrderedListSerializerDeserializer
and AUnorderdListSerializerDeserializer.
