Configuration Description
--warehouse
The path to Paimon warehouse.
--database
The database name in Paimon catalog.
--ignore_incompatible
It is default false, in this case, if MySQL table name exists in Paimon and their schema is incompatible,an exception will be thrown. You can specify it to true explicitly to ignore the incompatible tables and exception.
--table_mapping
The table name mapping between source database and Paimon. For example, if you want to synchronize a source table named "test" to a Paimon table named "paimon_test", you can specify "--table_mapping test=paimon_test". Multiple mappings could be specified with multiple "--table_mapping" options. "--table_mapping" has higher priority than "--table_prefix" and "--table_suffix".
--table_prefix
The prefix of all Paimon tables to be synchronized except those specified by "--table_mapping" or "--table_prefix_db". For example, if you want all synchronized tables to have "ods_" as prefix, you can specify "--table_prefix ods_".
--table_suffix
The suffix of all Paimon tables to be synchronized except those specified by "--table_mapping" or "--table_suffix_db". The usage is same as "--table_prefix".
--table_prefix_db
The prefix of the Paimon tables to be synchronized from the specified db. For example, if you want to prefix the tables from db1 with "ods_db1_", you can specify "--table_prefix_db db1=ods_db1_". "--table_prefix_db" has higher priority than "--table_prefix".
--table_suffix_db
The suffix of the Paimon tables to be synchronized from the specified db. The usage is same as "--table_prefix_db".
--including_tables
It is used to specify which source tables are to be synchronized. You must use '|' to separate multiple tables.Because '|' is a special character, a comma is required, for example: 'a|b|c'.Regular expression is supported, for example, specifying "--including_tables test|paimon.*" means to synchronize table 'test' and all tables start with 'paimon'.
--excluding_tables
It is used to specify which source tables are not to be synchronized. The usage is same as "--including_tables". "--excluding_tables" has higher priority than "--including_tables" if you specified both.
--including_dbs
It is used to specify the databases within which the tables are to be synchronized. The usage is same as "--including_tables".
--excluding_dbs
It is used to specify the databases within which the tables are not to be synchronized. The usage is same as "--excluding_tables". "--excluding_dbs" has higher priority than "--including_dbs" if you specified both.
--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.
--partition_keys
The partition keys for Paimon table. If there are multiple partition keys, connect them with comma, for example "dt,hh,mm". If the keys are not in source table, the sink table won't set partition keys.
--multiple_table_partition_keys
The partition keys for each different Paimon table. If there are multiple partition keys, connect them with comma, for example
  • --multiple_table_partition_keys tableName1=col1,col2.col3
  • --multiple_table_partition_keys tableName2=col4,col5.col6
  • --multiple_table_partition_keys tableName3=col7,col8.col9
  • If the keys are not in source table, the sink table won't set partition keys.
    --primary_keys
    The primary keys for Paimon table. If there are multiple primary keys, connect them with comma, for example "buyer_id,seller_id". If the keys are not in source table, but the source table has primary keys, the sink table will use source table's primary keys. Otherwise, the sink table won't set primary keys.
    --kafka_conf
    The configuration for Flink Kafka sources. Each configuration should be specified in the format `key=value`. `properties.bootstrap.servers`, `topic/topic-pattern`, `properties.group.id`, and `value.format` are required configurations, others are optional.See its document for a complete list of configurations.
    --catalog_conf
    The configuration for Paimon catalog. Each configuration should be specified in the format "key=value". See here for a complete list of catalog configurations.
    --table_conf
    The configuration for Paimon table sink. Each configuration should be specified in the format "key=value". See here for a complete list of table configurations.
