+
+| Name | Required | Default | Description |
+|------|----------|---------|-------------|
+| `seedHosts` | `true` | `null` | Comma seperated list of one or more
Aerospike cluster hosts; each host can be specified as a valid IP address or
hostname followed by an optional port number (default is 3000). |
+| `keyspace` | `true` | `null` | Aerospike namespace to use. |
+| `keySet` | `false` | `null` | Aerospike set name to use. |
+| `columnName` | `true` | `null` | Aerospike bin name to use. |
+| `maxConcurrentRequests` | `false` | `100` | Maximum number of concurrent
Aerospike transactions that a Sink can open. |
+| `timeoutMs` | `false` | `100` | A single timeout value controls
`socketTimeout` and `totalTimeout` for Aerospike transactions. |
+| `retries` | `false` | `1` | Maximum number of retries before aborting a
write transaction to Aerospike. |
