Struct LocalStorage 

pub struct LocalStorage { /* private fields */ }

Per-transaction local storage for all modified tables.

Implementations

impl LocalStorage

pub fn new() -> Self

pub fn get_or_create_table(&mut self, table_id: u64) -> &mut LocalTableData

pub fn get_table(&self, table_id: u64) -> Option<&LocalTableData>

pub fn len(&self) -> usize

Number of tables with buffered data.

pub fn is_empty(&self) -> bool

pub fn flush_to_tables( &self, catalog: &Arc<TableCatalog>, txn_id: Option<u64>, ) -> Result<Vec<UndoRecord>, StorageError>

Flush all buffered writes to the actual tables via the TableCatalog.

Called on commit. After a successful flush, the transaction’s writes are visible to subsequent transactions. When txn_id is Some(...), inserts/deletes are recorded in VersionInfo. Returns undo records for potential rollback.

pub fn clear(&mut self)

Clear all buffered data (called on rollback).
