|:----------------------------|:---------|:------------------|:----------------------|
| `node['cayley']['version']` | String | `0.3.0` | Version of Cayley to manage. |
| `node['cayley']['backend']` | String | `mem` | Determines the type of the underlying database. (`mem`|`leveldb`|`mongodb`) |
| `node['cayley']['directory']` | String | `/opt/cayley` | Directory for Cayley to be installed |
| `node['cayley']['listen_host']` | String | `0.0.0.0` | The hostname or IP address for Cayley's HTTP server to listen on. |
| `node['cayley']['listen_port']` | String | `64210` | The port for Cayley's HTTP server to listen on. |
| `node['cayley']['read_only']` | Boolean | `false` | If true, disables the ability to write to the database using the HTTP API. |
| `node['cayley']['log_dir']` | String | `/var/log/cayley` | Location to store runtime and error log messages. |

### Per-Database Options

|:---------------------------------------------------|:----------|:------------|:----------------------|
| `node['cayley']['db_options']['write_buffer_mb']` | Integer | `20` | The size in MiB of the LevelDB write cache. Increasing this number allows for more/faster writes before syncing to disk. Default is 20, for large loads, a recommended value is 200+. |
| `node['cayley']['db_options']['cache_size_mb']` | Integer | `2` | The size in MiB of the LevelDB block cache. Increasing this number uses more memory to maintain a bigger cache of triple blocks for better performance. |
