Configuration Description
--warehouse
The path to Paimon warehouse.
--database
The database name in Paimon catalog.
--table
The Paimon table name.
--partition_keys
The partition keys for Paimon table. If there are multiple partition keys, connect them with comma, for example "dt,hh,mm".
--primary_keys
The primary keys for Paimon table. If there are multiple primary keys, connect them with comma, for example "buyer_id,seller_id".
--type_mapping
It is used to specify how to map MySQL data type to Paimon type.
Supported options:
  • "tinyint1-not-bool": maps MySQL TINYINT(1) to TINYINT instead of BOOLEAN.
  • "to-nullable": ignores all NOT NULL constraints (except for primary keys). This is used to solve the problem that Flink cannot accept the MySQL 'ALTER TABLE ADD COLUMN column type NOT NULL DEFAULT x' operation.
  • "to-string": maps all MySQL types to STRING.
  • "char-to-string": maps MySQL CHAR(length)/VARCHAR(length) types to STRING.
  • "longtext-to-bytes": maps MySQL LONGTEXT types to BYTES.
  • "bigint-unsigned-to-bigint": maps MySQL BIGINT UNSIGNED, BIGINT UNSIGNED ZEROFILL, SERIAL to BIGINT. You should ensure overflow won't occur when using this option.
  • "decimal-no-change": Ignore decimal type change.
