Currently, MySQL SourceRecordEmitter treats FLOAT(x) (float with explicit precision) as a DOUBLE, but pipeline MetadataAccessor reports a plain "FLOAT", which causes discrepancy and corrupted deserialized data.

This bug should be fixed by adjusting MetadataAccessor logic (mapping FLOAT(x) to DOUBLE).
