[Obsolete("Use Google.Cloud.Spanner.V1.SessionPool.SessionPoolSegmentStatistics instead. The behavior of both classes is the same, but the new class name better reflects the fact that sessions are now pooled by aspects other than database name.")]
public sealed class DatabaseStatisticsReference documentation and code samples for the Google Cloud Spanner v1 API class SessionPool.DatabaseStatistics.

Properties
ActiveSessionCount
public int ActiveSessionCount { get; }The number of active or requested sessions. This is the difference between the number of successful or pending session acquisition requests and the number of released sessions.
