The SSTable Output step writes to a filesystem directory as a Cassandra SSTable.
Option | Definition |
|---|---|
Step name | The name of this step as it appears in the transformation workspace. |
Cassandra yaml file | Location of yaml file. A cassandra.yaml file is the main configuration file for Cassandra and defines node and cluster configuration details. |
Directory | Location to write the output to. This directory points to the target table to load to and must match the Keyspace field. |
Keyspace | Name of the keyspace of the target table to load to. This name must match the Directory field. |
Column family (table) | Name of the table to upload to. This assumes the metadata for this table was previously defined in Cassandra. |
Incoming field to use as the row key | Allows you to select which incoming row to use as the row key. This drop-down box will be populated with the names of incoming transformation fields. |
Buffer (MB) | The buffer size to use. A new table file is written every time the buffer is full. |
