Migrate data to Hyper-Converged Database (HCD)
Hyper-Converged Database (HCD) uses several solutions for migrating data from other databases:
-
Use DataStax Bulk Loader (dsbulk) to load and unload CSV or JSON data in and out of the HCD database.
-
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 HCD and write CSV data from HCD 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.
