Structs

CommittedTransaction

This is the result of a successfully committed Transaction. One can retrieve the post_commit_stats, commit version, and optionally the post-commit snapshot from this struct.

ConflictedTransaction

This is the result of a conflicted Transaction. One can retrieve the conflict version from this struct. In the future a rebase API will be provided (issue #1389).

CreateTable

Marker type for create-table transactions.

ExistingTable

Marker type for transactions on existing tables.

PostCommitStats

Kernel exposes information about the state of the table that engines might want to use to trigger actions like checkpointing or log compaction. This struct holds that information.

RetryableTransaction

A transaction that failed to commit due to a retryable error (e.g. IO error). The transaction can be recovered with RetryableTransaction::transaction and retried without rebasing. The associated error can be inspected via RetryableTransaction::error.

Transaction

A transaction represents an in-progress write to a table. After creating a transaction, changes to the table may be staged via the transaction methods before calling commit to commit the changes to the table.

WriteContext

WriteContext is data derived from a Transaction that can be provided to writers in order to write table data.

Enums

CommitResult

The result of attempting to commit this transaction. If the commit was successful/conflicted/retryable, the result is Ok(CommitResult), otherwise, if a nonrecoverable error occurred, the result is Err(Error).
