Variants

Put

Fields

table_id: u64

rows: Vec<u8>

Delete

Fields

table_id: u64

row_ids: Vec<RowId>

TruncateTable

Fields

table_id: u64

Flush

System marker (txn_id == SYSTEM_TXN_ID): everything up to flushed_epoch for table_id is durable in a sorted run, so recovery may skip replaying older records for that table.

Fields

table_id: u64

flushed_epoch: u64

TxnCommit

Seals a transaction: every earlier record with the same txn_id is committed and becomes visible at epoch.

Fields

epoch: u64

added_runs: Vec<AddedRun>

TxnAbort

Aborts a transaction; its staged records are discarded on recovery.

Ddl(DdlOp)
