Module transaction

Modules§

builderinternal-api: Builder modules for transaction construction.
create_tableinternal-api: Create table transaction types and entry point (internal API).
data_layoutinternal-api: Data layout configuration for Delta tables.

AlterTable: Marker type for alter-table (schema evolution) transactions.
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: A write context for a specific partition or an unpartitioned table. Created by Transaction::partitioned_write_context or Transaction::unpartitioned_write_context.

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).

SupportsDataFiles: Marker trait for transaction states that support data file operations.
