MySQL to Greenplum Data Synchronization | NineData

Greenplum is often used for analytical workloads that are too heavy for a transactional MySQL database. NineData Data Replication supports schema replication, full replication, and incremental replication from MySQL-compatible data sources to Greenplum, helping teams move operational data into an analytics warehouse.

When to use this workflow​

Use this workflow to:

  • Load MySQL business data into Greenplum for reporting or large-scale analytics.
  • Initialize Greenplum table structures and data from MySQL.
  • Keep Greenplum updated with incremental MySQL changes after the full load.
  • Map data types and table structures between MySQL and Greenplum.
  • Validate replicated data before downstream systems depend on it.

For detailed prerequisites, permissions, data type mapping, and task settings, see MySQL to Greenplum.

Before you begin​

Prepare the following items:

  • Access to the NineData console.
  • Connection information and accounts for the MySQL source and Greenplum target.
  • Binlog enabled on the MySQL source when incremental replication is required.
  • Required permissions on both systems.
  • Network connectivity from NineData to both systems.
  • A target design that defines how MySQL tables should map to Greenplum.

Procedure​

  1. Add the MySQL source data source to NineData.
  2. Add the Greenplum target data source to NineData.
  3. Create a data replication task from MySQL to Greenplum.
  4. Select the replication types required for your workload:
    • Schema Replication to create target structures.
    • Full Replication to load existing source data.
    • Incremental Replication to keep Greenplum updated after the full load.
  5. Select source objects and configure mapping or filtering if needed.
  6. Run the precheck. Fix any failed item before starting the task.
  7. Start the task and monitor replication progress, delay, and task logs.
  8. Use data comparison when consistency validation is required.

Result​

After the task starts, NineData initializes the selected MySQL data in Greenplum and keeps the target updated through incremental replication if you selected it. When validation passes, the Greenplum target can be used for analytics, reporting, and downstream warehouse workloads.
