## Constructors

### CreateReadSessionRequest()

    public CreateReadSessionRequest()

### CreateReadSessionRequest(CreateReadSessionRequest)

    public CreateReadSessionRequest(CreateReadSessionRequest other)

| **Parameter** ||
|---|---|
| **Name** | **Description** |
| `other` | `https://docs.cloud.google.com/dotnet/docs/reference/Google.Cloud.BigQuery.Storage.V1/latest/Google.Cloud.BigQuery.Storage.V1.CreateReadSessionRequest` |

## 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.

|---|---|
| **Type** | **Description** |
| `https://learn.microsoft.com/dotnet/api/system.int32` |   |

### Parent

    public string Parent { get; set; }

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

| **Property Value** ||
|---|---|
| **Type** | **Description** |
| `https://learn.microsoft.com/dotnet/api/system.string` |   |

### ParentAsProjectName

    public ProjectName ParentAsProjectName { get; set; }

[ProjectName](https://cloud.google.com/dotnet/docs/reference/Google.Api.Gax/latest/Google.Api.Gax.ResourceNames.ProjectName.html)-typed view over the [Parent](https://docs.cloud.google.com/dotnet/docs/reference/Google.Cloud.BigQuery.Storage.V1/latest/Google.Cloud.BigQuery.Storage.V1.CreateReadSessionRequest#Google_Cloud_BigQuery_Storage_V1_CreateReadSessionRequest_Parent) resource name property.

|---|---|
| **Type** | **Description** |
| `https://cloud.google.com/dotnet/docs/reference/Google.Api.Gax/latest/Google.Api.Gax.ResourceNames.ProjectName.html` |   |

### 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.

|---|---|
| **Type** | **Description** |
| `https://learn.microsoft.com/dotnet/api/system.int32` |   |

### ReadSession

    public ReadSession ReadSession { get; set; }

Required. Session to be created.

| **Type** | **Description** |
| `https://docs.cloud.google.com/dotnet/docs/reference/Google.Cloud.BigQuery.Storage.V1/latest/Google.Cloud.BigQuery.Storage.V1.ReadSession` |   |
