MySQL to Paimon

BladePipe supports data replication from MySQL to Paimon. View supported migration, sync, verification, and connector capabilities.

Target DataSource：

Paimon

Connection

Function	Description
Schema Migration	If the target schema does not exist, BladePipe will automatically generate and execute CREATE statements based on the source metadata and the mapping rule.
Full Data Migration	Migrate data by sequentially scanning data in tables and writing it in batches to the target database.
Incremental Data Sync	Sync of common DML like INSERT, UPDATE, DELETE is supported. UPDATE and DELETE for tables without primary keys are not synced by default (manual selection required).
Subscription Modification	Add, delete, or modify the subscribed tables with support for historical data migration. For more information, see Modify Subscription.
Position Resetting	Reset positions by file position or timestamp. Allow re-consumption of incremental data logs in a past period or since a specific Binlog file and position.
Table Name Mapping	Support the mapping rules, namely, keeping the name the same as that in Source, converting the text to lowercase, converting the text to uppercase, truncating the name by "_digit" suffix.
DDL Sync	ALTER TABLE ADD COLUMN, DROP COLUMN, MODIFY COLUMN, CHANGE COLUMN
Metadata Retrieval	Retrieve the target metadata with filtering conditions or target primary keys set from the source table.

Function	Description
Write Conflict Resolution Rule	For the source tables with primary keys, data is overwritten to the Target. For the source tables without primary keys, data is appended to the Target.
Custom Table Properties	Configure format-version and other table properties.
Setting Data Partitions	When creating a DataJob, specify partition definitions at the table level (separated by comma). Automatically add these partition definitions during schema migration.
Custom Code	For more information, see Custom Code Processing, Debug Custom Code and Logging in Custom Code.
Setting Target Primary Key	Change the primary key to another field to facilitate data aggregation and other operations.
Data Filtering Conditions	Support data filtering using WHERE conditions, with SQL-92 as the SQL language. For more information, see Data Filtering.

Limit	Description
MySQL Storage Engine	Support InnoDB, MyISAM, AWS XEngine. Other storage engines have not been tested yet.
MySQL Character Set	Support utf8, utf8mb4, latin1. Other encodings have not been tested yet.

Prerequisite	Description
Permissions for Account	See Permissions Required for MySQL/MariaDB.
Enabling Binlog	[mysqld] log-bin=mysql-bin # Enable Binlog binlog-format=ROW # Choose ROW mode binlog_row_image=FULL # Changes include all column data

Parameter	Description
parseBinlogParallel	Number of threads for parallel parsing of Binlog in Incremental DataJobs.
parseBinlogBufferSize	Size of the circular buffer for parsing Binlog in Incremental DataJobs.
maxTransactionSize	Maximum number of data rows per transaction. If exceeded, the transaction will be split and flushed in parts.
limitThroughputMb	Limit the throughput of incremental Binlogs.
extraDDL	Support synchronization of additional DDL, including PT, GHOST, ALI_DMS, and PT_GHOST.
needJsonEscape	Escape special characters in JSON to be written to the target database.
fullDataSqlConditionEnabled	Add filtering conditions in SQL during source data scanning. It only works in Full Data migration.
srcTimeZone	Source time zone, e.g., +08:00, Asia/Shanghai, America/New_York, etc.

Tips: To modify the general parameters, see General Parameters and Functions.

Prerequisite	Description
Port Preparation	Allow the migration and sync node (Worker) to connect to the Catalog and Warehouse.
S3 Catalog Configuration Template	CatalogUri: glue.ap-southeast-1.amazonaws.com httpsEnabled: true metastoreType: filesystem warehouse : s3://warehouse/test catalogProps: { "s3.access-key": "", "s3.secret-key": "", "s3.path-style-access": "true" }

Parameter	Description
writeParallel	The number of parallel threads allowed to write data to the Target, significantly affecting migration or synchronization performance.
writeProps	Write configuration (Json format)
compactTaskSize	Compression task thread count
paimonIOManagerPaths	I/O manager path
defaultDynamicBucket	Default dynamic Bucket count
totalDataInMemMb	Maximum data size allowed in memory when writing in batches; If the data size exceeds the memory limit, or the wait time exceeds asyncFlushIntervalSec, then data is flushed to the write queue.
asyncFlushIntervalSec	Interval to wait for flushing when writing in batches; If the wait time exceeds asyncFlushIntervalSec, or the data size exceeds totalDataInMemMb, then data is flushed to the write queue.
flushBatchMb	Maximum batch size per table; If the batch size exceeds this limit, then data is flushed to the write queue.
realFlushPauseSec	Wait time to flush data to Paimon. 0 means no wait is needed.
catalogUri	Catalog URI
httpsEnabled	Enable HTTPS for Catalog URI
catalogWarehouse	Specify the root directory URI of the Paimon warehouse
catalogMetastoreType	Enable file system mode
catalogProps	Catalog configuration
enableTimeZoneProcess	Whether to convert time zone on time fields
timezone	Target time zone, e.g., +08:00, Asia/Shanghai, America/New_York, etc.
