-| `kinesis.partitionKey` | A partition key is used to group data by shard within a stream. A Kinesis Data Stream uses the partition key that is associated with each data record to determine which shard a given data record belongs to. For example, if your logs come from Docker containers, you can use container_id as the partition key, and the logs will be grouped and stored on different shards depending upon the id of the container they were generated from. As the data within a shard are coarsely ordered, you will get all your logs from one container in one shard roughly in order. If you don't set a partition key or put an invalid one, a random key will be generated, and the logs will be directed to random shards. If the partition key is invalid, the plugin will print an warning message. | `"container_id"` |
