…QL-CDC source
The `int_type_narrowing` option is documented for the MySQL-CDC source
(including a `false` example) and declared in MySqlIncrementalSourceFactory's
option rule, but it had no effect on the CDC path, for two reasons:
1. MySqlTypeUtils built the column type from Debezium's bare type name
("TINYINT") and never re-appended the length, so MySqlTypeConverter's narrowing
check (columnType.equalsIgnoreCase("tinyint(1)")) never matched — tinyint(1)
could not be detected on the CDC path.
2. convertToSeaTunnelColumn always used MySqlTypeConverter.DEFAULT_INSTANCE
(narrowing = true), ignoring the configured value.
This change:
- re-appends the length for TINYINT so tinyint(1) is detectable; and
- carries int_type_narrowing through the Debezium properties and selects the
converter: true (default) -> tinyint(1) narrows to BOOLEAN (matching the JDBC
source and the documented default); false -> tinyint(1) stays TINYINT (Byte).
Adds MySqlTypeUtilsIntTypeNarrowingTest covering true / false / default.
