In addition to the configuration of some of the default modules in [Configuration](Configuration.html), the overlord module requires the following basic configs to run in remote mode:
In addition to the configuration of some of the default modules in [Configuration](Configuration.html), the overlord has the following basic configs:
|Property|Description|Default|
|Property|Description|Default|
|--------|-----------|-------|
|--------|-----------|-------|
|`druid.indexer.runner.type`|Choices "local" or "remote". Indicates whether tasks should be run locally or in a distributed environment.|local|
|`druid.indexer.runner.type`|Choices "local" or "remote". Indicates whether tasks should be run locally or in a distributed environment.|local|
|`druid.indexer.storage.type`|Choices are "local" or "db". Indicates whether incoming tasks should be stored locally (in heap) or in a database. Storing incoming tasks in a database allows for tasks to be bootstrapped if the overlord should fail.|local|
|`druid.indexer.storage.type`|Choices are "local" or "db". Indicates whether incoming tasks should be stored locally (in heap) or in a database. Storing incoming tasks in a database allows for tasks to be resumed if the overlord should fail.|local|
|`druid.indexer.queue.maxSize`|Maximum number of active tasks at one time.|Integer.MAX_VALUE|
|`druid.indexer.queue.startDelay`|Sleep this long before starting overlord queue management. This can be useful to give a cluster time to re-orient itself after e.g. a widespread network issue.|PT1M|
|`druid.indexer.queue.restartDelay`|Sleep this long when overlord queue management throws an exception before trying again.|PT30S|
|`druid.indexer.queue.storageSyncRate`|Sync overlord state this often with an underlying task persistence mechanism.|PT1M|
The following configs only apply if the overlord is running in remote mode:
