Step 3: Run the Amazon Glue job to export the Amazon Keyspaces table to the Amazon S3 bucket from the Amazon CLI - Amazon Keyspaces (for Apache Cassandra)
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Step 3: Run the Amazon Glue job to export the Amazon Keyspaces table to the Amazon S3 bucket from the Amazon CLI

In this step, you use the Amazon CLI to run the Amazon Glue job created in the previous step to export an Amazon Keyspaces table to your bucket in Amazon S3.

Run the export job from the Amazon CLI

  1. In the following example, the Amazon CLI command runs the job created in the previous step.

    aws glue start-job-run --job-name AmazonKeyspacesExportToS3-cfn-setup-cfn-glue

    • You can override any of the Amazon Glue job parameters including the default arguments in the Amazon CLI command. To override any default arguments of the job, for example keyspace or table name, you can pass them as arguments. For a full list of arguments, see start-job-run in the Amazon Glue Command Line Reference.

      The following command runs the Amazon Glue export job, but overrides the number of Amazon Glue workers, worker type, and the table name. 

      aws glue start-job-run --job-name AmazonKeyspacesExportToS3-cfn-setup-cfn-glue \
                    --number-of-workers 8 --worker-type G.2X \
                    --arguments '{"--TABLE_NAME":"my_table"}'

  2. Confirm that your table has been exported to your Amazon S3 bucket. Based on the size of the table, this can take some time. When the export job is finished, you can see the following folders in the bucket using the example command.

    aws s3 ls s3://s3-keyspaces

    The output shows the following structure in your bucket.

                               PRE conf/
                           PRE export/
                           PRE jars/
                           PRE scripts/
                           PRE spark-logs/

    Your files will be located in the following folder structure under export, data/time values will show your own values.

    \------- export
                \----- keyspace_name
                    \----- table_name
                       \----- snapshot
                           \----- year=2025 
                               \----- month=01
                                  \----- day=02
                                      \----- hour=09
                                          \----- minute=22
                                              \--- YOUR DATA HERE

To schedule the Amazon Glue job you just ran manually, proceed to Step 4: (Optional) Create a trigger to schedule the export job.
