In the below example, the data is captured from the source table named invoice and is written to the Redis database as a hash. The connection is an optional parameter that must refer to the corresponding connection name defined in config.yaml. When the data_type parameter is specified for the job, it overrides the system-wide setting target_data_type (defined in config.yaml).

In this case, the results will be Redis hashes with keys based on the key expression (e.g. invoice_id:1) and the expiration set to 100 seconds for each key. If no expire parameter is given, the keys will never expire.
