> I am attempting to deserialize {{RexNodes}} that contain non-standard operators but {{RexJson#toOp}} only considers operators found in {{{}SqlStdOperatorTable{}}}: [https://github.com/apache/calcite/blob/c945b7f49b99538748c871557f6ac80957be2b6e/core/src/main/java/org/apache/calcite/rel/externalize/RelJson.java#L780]
> For example, attempting to deserialize a JSON RexCall that includes the BigQuery only `DATE_FROM_UNIX_DATE` operator raises {{CalciteException: No operator for 'DATE_FROM_UNIX_DATE' with kind: 'OTHER_FUNCTION', syntax: 'FUNCTION' during JSON deserialization}}
> Unless I am missing something, I don't believe the operator lookup is configurable or overridable.
