Expand description

Group-commit operations on top of an AutoCommitBatchWindow. The window is shared with AutoCommitBatchOps; bind_auto_commit_statement is mode-aware: bound inside a group window it reuses the shared write timestamp and undo log, so no separate bind method is needed.

Required Methods§

Source

fn begin_auto_commit_group(&self) -> StorageResult<Arc<AutoCommitBatchWindow>>

Open a group window (gate + shared snapshots + shared write timestamp).

Source

fn finalize_auto_commit_group( &self, window: &AutoCommitBatchWindow, ) -> StorageResult<()>

Single group commit point: one fsync, barrier advance, one ts commit.

Provided Methods§

Source

fn rollback_auto_commit_group( &self, _window: &AutoCommitBatchWindow, ) -> StorageResult<()>

Roll back every statement bound to this group via its shared undo log, then release the window’s snapshots and gate. Default: not supported.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
