SingleStore as Target

Fivetran HVR supports integrating changes into SingleStore location. This section describes the configuration requirements for integrating changes (using Integrate and Refresh) into SingleStore location. For the list of supported SingleStore versions into which HVR can integrate changes, see Integrate changes into location in Capabilities.

HVR connects to the SingleStore server using the TCP protocol.

HVR uses MariaDB's native Connector/C interface to write data into SingleStore during Continuous Integrate and Row-wise Refresh.

The preferred methods for writing data into SingleStore are using Burst Integrate and Bulk Refresh as they provide better performance. However, it is required to create staging files on a temporary location to perform Burst Integrate and Bulk Refresh. For more information about staging, see section Staging for SingleStore.
