Advanced Configuration
Configure Pebble Flow to meet your processing needs.
Depending on the computational complexity of your spreadsheets, you may need to change your server's default configuration settings.
| Environment Variable | Default Value | Comments | Server Type |
|---|---|---|---|
| CALLBACK_MAX_RETRY_COUNT | 5 | The maximum number of times the server will attempt a requested service callback. | worker |
| JOBS_IDLE_TIME | 10000 | The time in milliseconds the server will wait before checking for a job when the jobs queue is empty. | worker |
| REQUESTS_IDLE_TIME | 10000 | The time in milliseconds the server will wait before checking for a request when the requests queue is empty. | worker |
| SCENARIOS_IDLE_TIME | 10000 | The time in milliseconds the server will wait before checking for a scenario when the scenarios queue is empty. | worker |
| PEBBLE_CACHE_SIZE | 32 | The number of pebbles stored in the pebble cache. Pebbles already loaded in memory are initialized faster by the server. Note that each server node has a separate pebble cache. If your library of Pebbles exceeds this number by a factor of 5, it may make sense to increase this value. Consider the size of your Pebble Flow Server nodes when changing this value. | worker |
| RUNNER_PROCESSOR_RATIO | 1.5 | This ratio is multiplied by the number of core processors to obtain the size of the thread pool that runs pebbles. For instance if there are four cores and this value is set to 1.5, the thread pool size will be 6 (1.5 x 4). Consider the thread-to-memory ratio when setting this value. Lower this value If your computations are memory-intensive. Increase this value is your computations are small in size but you have many of them to complete. | worker |
| DATA_CACHE_SIZE | 256 | The number of data files stored in memory when executing a workflow. Once loaded, data files can be reused. This is useful for speeding up group-level calculations, where a single data file may contain multiple groups. Care should be used when setting this value, as it is not possible to estimate data file sizes accurately. Consider the size of your Pebble Flow Server nodes and the characteristics of your workflows when changing this value. | worker |
| PROCESSING_WAITING_TIME | 1000 | The duration the server will wait, in milliseconds, before checking on the status of a set of running pebbles' completion. Setting this value to a smaller number increases the frequency of completion checks. | worker |
| REQUEST_TIMEOUT_IN_SECONDS | 600 | Pebble Flow no longer leases messages. Messages are deleted as soon as they are pulled from the queue. | DEPRECATED |
| STORAGE_PASSWORD | - | Set when configuring for deployment. | |
| WORKFLOW_TIMEOUT_DURATION_IN_SECONDS | 43200 | The time in seconds the server will allow a workflow to complete without aborting the execution. | orchestrator |
| JOBS_IDLE_TIME | 250 | The time in milliseconds the server will wait to check for more messages when the orchestrator queue is empty. | orchestrator |
