LiveTableData

Struct LiveTableData 

Source
pub struct LiveTableData { /* private fields */ }
Expand description

Wraps a table’s data so we can dynamically push new batches. The MemTable is created on initialization and shared with queries.

Implementations§

Source§

impl LiveTableData

Source

pub async fn push(&self, batch: RecordBatch)

Push a new batch to the table.

Source

pub async fn apply_retention( &self, table_name: &str, where_clause: &str, ) -> Result<()>

Filter the table’s data, keeping only rows that match the WHERE clause.

Holds the write lock for the entire operation to prevent data loss from concurrent push() calls.

Source

pub fn schema(&self) -> SchemaRef

Get the schema.

Source

pub fn mem_table(&self) -> Arc<MemTable>

Get the MemTable for registering with a SessionContext.
