Migrating data to DataStax Enterprise

Methods to migrate data to DataStax Enterprise solutions.

DataStax Enterprise (DSE) uses several solutions for migrating data from other databases:

  • The CQL COPY TO command mirrors what the PostgreSQL RDBMS uses for file/export import.

    You can use COPY in the CQL shell to read CSV data to DSE and write CSV data from DSE to a file system. Typically, an RDBMS has unload utilities for writing table data to a file system.

  • The sstableloader provides the ability to bulk load external data into a cluster.

ETL tools

If you need more sophistication applied to a data movement situation than just extract-load, you can use any number of extract-transform-load (ETL) solutions that support DataStax Enterprise. These tools provide transformation routines for manipulating source data and then loading the data into a DSE target. The tools offer features such as visual, point-and-click interfaces, scheduling engines, and more.

Many ETL vendors who support DSE supply community editions of their products that are free and able to solve many different use cases. Enterprise editions are also available.

You can download ETL tools that work with DSE from Jaspersoft, Pentaho, and Talend.
