      Description

      I have a json file of a size about 2MB.

      There's no issue loading it CONNECT tables. However I got "Out of memory" error when trying to read the tables.

      Here's the query:

       SELECT * 
       FROM `era_stage`.`era_stage_bpr_financial_information_0`  bpr
       JOIN `era_stage`.`era_stage_trn_trace_number_0`  trn ON trn.trace_number_id = bpr.financial_information_id
       JOIN `era_stage`.`era_stage_n1_entity_identification_0`  n1 ON n1.parent_id = bpr.financial_information_id;
      

      Each table above only have 1 or 2 records.

      if I remove any of the JOINs, the query executed with no problem.

      But with both JOINs, it gave me this error "Got error 174 'ParseString: Out of memory' from CONNECT".

      As the query is expected to return only a couple records, the error message is kind of confusing. I did try increasing `connect_work_size` to 536870912 (512M) though, didn't help. Wonder if it has anything to do with memory.

      I attached sql dump for you test the query above.
