Properties

MaxStreamCount

public int MaxStreamCount { get; set; }

Max initial number of streams. If unset or zero, the server will provide a value of streams so as to produce reasonable throughput. Must be non-negative. The number of streams may be lower than the requested number, depending on the amount parallelism that is reasonable for the table. There is a default system max limit of 1,000.

This must be greater than or equal to preferred_min_stream_count. Typically, clients should either leave this unset to let the system to determine an upper bound OR set this a size for the maximum "units of work" it can gracefully handle.

Property Value
TypeDescription
Int32

Parent

public string Parent { get; set; }

Required. The request project that owns the session, in the form of projects/{project_id}.

Property Value
TypeDescription
String

ParentAsProjectName

public ProjectName ParentAsProjectName { get; set; }

ProjectName-typed view over the Parent resource name property.

Property Value
TypeDescription
ProjectName

PreferredMinStreamCount

public int PreferredMinStreamCount { get; set; }

The minimum preferred stream count. This parameter can be used to inform the service that there is a desired lower bound on the number of streams. This is typically a target parallelism of the client (e.g. a Spark cluster with N-workers would set this to a low multiple of N to ensure good cluster utilization).

The system will make a best effort to provide at least this number of streams, but in some cases might provide less.

Property Value
TypeDescription
Int32

ReadSession

public ReadSession ReadSession { get; set; }

Required. Session to be created.
