		Long: `Instance Pools API are used to create, edit, delete and list instance pools by
  using ready-to-use cloud instances which reduces a cluster start and
  auto-scaling times.
  
  Databricks pools reduce cluster start and auto-scaling times by maintaining a
  set of idle, ready-to-use instances. When a cluster is attached to a pool,
  cluster nodes are created using the pool’s idle instances. If the pool has
  no idle instances, the pool expands by allocating a new instance from the
  instance provider in order to accommodate the cluster’s request. When a
  cluster releases an instance, it returns to the pool and is free for another
  cluster to use. Only clusters attached to a pool can use that pool’s idle
  instances.
  
  You can specify a different pool for the driver node and worker nodes, or use
  the same pool for both.
  
  Databricks does not charge DBUs while instances are idle in the pool. Instance
  provider billing does apply. See pricing.`,
