Write to a Redis hash

In the following example, the data is captured from the source table named invoice and is written to the Redis database as hash keys. 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 key names based on the key expression (e.g., invoice_id:1) and with an expiration of 100 seconds. If no expire parameter is given, the keys will never expire.

source:
  server_name: chinook
  schema: public
  table: invoice
output:
  - uses: redis.write
    with:
      connection: target
      data_type: hash
      key:
        expression: concat(['invoice_id:', InvoiceId])
        language: jmespath
      expire: 100
