From discord @pepijnve : `l_returnflag and l_linestatus are both char(1)` I think this is an interasting obervation as well - `l_returnflag` and `l_linestatus` could: * be packed into a single 16-bit value * use single column aggregation instead of the slower multi column aggregation * and (if beneficial) use direct indexing (only 65K values) instead of hashing/lookup table. -- This is an automated message from the Apache Git Service.
