[−][src]Struct gcp_client::google::cloud::bigquery::storage::v1beta1::CreateReadSessionRequest
Creates a new read session, which may include additional options such as requested parallelism, projection filters and constraints.
Fields
table_reference: Option<TableReference>
Required. Reference to the table to read.
parent: String
Required. String of the form projects/{project_id}
indicating the
project this ReadSession is associated with. This is the project that will
be billed for usage.
table_modifiers: Option<TableModifiers>
Any modifiers to the Table (e.g. snapshot timestamp).
requested_streams: i32
Initial number of streams. If unset or 0, we 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 and the maximum amount of parallelism allowed by the system.
Streams must be read starting from offset 0.
read_options: Option<TableReadOptions>
Read options for this session (e.g. column selection, filters).
format: i32
Data output format. Currently default to Avro.
sharding_strategy: i32
The strategy to use for distributing data among multiple streams. Currently defaults to liquid sharding.
Implementations
impl CreateReadSessionRequest
[src]
pub fn format(&self) -> DataFormat
[src]
Returns the enum value of format
, or the default if the field is set to an invalid enum value.
pub fn set_format(&mut self, value: DataFormat)
[src]
Sets format
to the provided enum value.
pub fn sharding_strategy(&self) -> ShardingStrategy
[src]
Returns the enum value of sharding_strategy
, or the default if the field is set to an invalid enum value.
pub fn set_sharding_strategy(&mut self, value: ShardingStrategy)
[src]
Sets sharding_strategy
to the provided enum value.
