  #     distinct servers.
  # @!attribute [rw] per_server_session_count
  #   @return [::Integer]
  #     Soft maximum for how many sessions are allowed per server. Normally, the
  #     client will ensure that it does not host more than this count of sessions
  #     per server, unless there are other limits encountered (e.g. the connected
  #     servers is already at max_servers).

  # Configuration for the session pools. Session pools are tied to a scope

  # @!attribute [rw] headroom
  #   @return [::Float]
  #     Fraction of idle sessions to keep in order to manage an increase in
  #     requests-in-flight. For example, a headroom of 0.5 will keep enough
  #     sessions to deal with a 50% increase in QPS.
  # @!attribute [rw] min_session_count
  #   @return [::Integer]
  #     The minimum number of sessions for a given scope.
  # @!attribute [rw] max_session_count
  #   @return [::Integer]
  #     The maximum number of sessions for a given scope.
  # @!attribute [rw] new_session_queue_length
  #   @return [::Integer]
  #     Number of vRPCs that can be queued per starting session.
  # @!attribute [rw] new_session_creation_budget
  #   @return [::Integer]
  #     How many concurrent session establishments are allowed. The client will
  #     hold onto a count against this budget whenever it is establishing a new
  #     session, and release that count once the session is successfully
  #     established or failed to establish.
  # @!attribute [rw] new_session_creation_penalty
  #   @return [::Google::Protobuf::Duration]
  #     How long to penalize the creation budget for a failed session creation
  #     attempt.
  # @!attribute [rw] consecutive_session_failure_threshold
  #   @return [::Integer]
  #     A threshold for cancelling all pending vRPCs based on how many
  #     consecutive session establishment errors have been observed. The client
  #     will eagerly cancel queued vRPCs after this threshold is met to avoid
  #     them waiting their entire deadlines before terminating (while waiting for
  #     any session to establish to actually send the vRPC).
  # @!attribute [rw] load_balancing_options
  #   @return [::Google::Cloud::Bigtable::V2::LoadBalancingOptions]
  #     How to balance vRPC load over connections to AFEs.
  #     Set only if session_load > 0.
