MariaDB to Redis

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

Target DataSource：

Redis

Connection

Function	Description
Full Data Migration	Migrate data by sequentially scanning data in tables and writing it in batches to the target database. The default data format is JSON.
Incremental Data Sync	Sync of common DML like INSERT, UPDATE, DELETE is supported.
Data Verification and Correction	Verify all existing data. Optionally, you can correct the inconsistent data based on verification results. Scheduled DataTasks are supported. For more information, see Create Verification and Correction DataJob. This function is not applicable to tables without primary keys.
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.

Function	Description
Cache Expiration Time	Allow setting the cache expiration time (in seconds) for data after it is written to Redis.
Concatenated Key	Form the target cache key by concatenating source database, table, and primary key value with colons.
JSON Data Format	Serialize structured source data into JSON format. Allow field name conversion based on the rules, such as keeping the name the same as that in Source, converting the text to lowercase, converting the text to uppercase, or camel case.

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 Redis/AWS ElastiCache port and Sentinel port (if available).

Parameter	Description
isSentinel	true represents Redis Sentinel Cluster, while false represents Single Node or Sharded Cluster.
sentinelUser	Username for connecting to Sentinel.
sentinelPassword	Password for connecting to Sentinel.
sentinelMasterName	Master Name specified in the Redis Sentinel configuration.
secondsToExpire	Use the set command to specify the expiration time of data written to the Target; -1 means no limit.
