  - About the Informix® JSON compatibility
    You can combine relational and JSON data into a single query by using the Informix® JSON compatibility features.
  - Wire listener
    The wire listener is a mid-tier gateway server that enables communication between MongoDB, REST API, and MQTT clients and the Informix® database server.
  - JSON data sharding
    You can shard data with HCL Informix®. Documents from a collection or rows from a table can be sharded across a cluster of database servers, reducing the number of documents or rows and the size of the index for the database of each server. When you shard data across database servers, you also distribute performance across hardware. As your database grows in size, you can scale up by adding more shard servers to your shard cluster.
