Engines

An engine represents a Dremio Cloud entity that manages compute resources. Each engine has one or more replicas that are created for executing queries. An engine replica is a logical group of executors defined by the engine size. This API allows you to list existing engines and add, modify, enable/disable, and delete engines.

Engines Attributes

Unique identifier of an engine.

Example e1cb20ff-a234-46f1-9f97-550e2bb5310f

The user-defined name for an engine.

Example firstEngine

The size of the engine. Each engine replica that is created will be of this size.

Enum XX_SMALL_V1, X_SMALL_V1, SMALL_V1, MEDIUM_V1, LARGE_V1, X_LARGE_V1, XX_LARGE_V1, XXX_LARGE_V1

Example SMALL_V1

The number of engine replicas that are currently active.

Example 0

The minimum number of engine replicas that will be enabled at any given time.

Example 0

The maximum number of engine replicas that will be enabled at any given time.

Example 10

The time (in seconds) that auto stop is delayed.

Example 300

The maximum amount of time (in seconds) that a query will wait in the engine’s queue before it is canceled.

Note: The typical time to start a new replica is two minutes (120 seconds), so we recommend setting this to more than 120 seconds. Changing this setting does not affect queries that are either currently running or already in the queue.

Example 300

The maximum amount of time (in seconds) that a query can run before being terminated.

Example 0

The maximum amount of time (in seconds) that an engine replica will continue to run after the engine is resized, disabled, or deleted before it is terminated and the running queries terminate.

Example 0

The current state of the engine.

Enum DELETING, DISABLED, DISABLING, ENABLED, ENABLING, INVALID

Example ENABLED

AWS tags.

Example {"key": "dremio", "value": "test"}

The date and time that the engine was last used to execute a query.

Example Thu Jan 01 00:00:00 UTC 2021

The date and time (in UTC time) that the state of the engine changed.

Example Thu Aug 19 14:39:40 UTC 2021

The description for the engine.

Example engine for sales workloads

The maximum number of concurrent queries that an engine replica can run.

Example 4

cloudTags

The key identifier for the tag.

Example dremio

The value of the tag.

Example test
