Struct MemSink 

pub struct MemSink {
    batches: Vec<PartitionData>,
    schema: SchemaRef,
}

Implements for writing to a MemTable

Fields

batches: Vec<PartitionData>

Target locations for writing data

schema: SchemaRef

Implementations

impl MemSink

pub fn try_new(batches: Vec<PartitionData>, schema: SchemaRef) -> Result<Self>

Creates a new MemSink.

The caller is responsible for ensuring that there is at least one partition to insert into.

Trait Implementations

impl DataSink for MemSink

fn as_any(&self) -> &dyn Any

Returns the data sink as Any so that it can be downcast to a specific implementation.

fn schema(&self) -> &SchemaRef

Returns the sink schema

fn write_all<'life0, 'life1, 'async_trait>( &'life0 self, data: SendableRecordBatchStream, _context: &'life1 Arc<TaskContext>, ) -> Pin<Box<dyn Future<Output = Result<u64>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Writes the data to the sink, returns the number of values written

fn metrics(&self) -> Option<MetricsSet>

Return a snapshot of the [MetricsSet] for this DataSink.

impl Debug for MemSink

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl DisplayAs for MemSink

fn fmt_as(&self, t: DisplayFormatType, f: &mut Formatter<'_>) -> Result

Format according to DisplayFormatType, used when verbose representation looks different from the default one
