    InsertLog
     
    StreamReadScope
    What a consuming DML's stream read actually SAW, captured at read time so the commit can advance the stream past exactly that — and nothing more.
    TableLock
    One table-level lock a transaction is HOLDING, as SHOW LOCKS reports it (live-verified): partition-rewriting DML — UPDATE, DELETE (even one matching no rows), MERGE, TRUNCATE — registers a PARTITIONS lock on the table's fully qualified name, one row per (transaction, table) however many statements touch it, released when the transaction ends.
    Transaction
     
    TransactionLog
     
    TransactionManager
     
    TransactionState
    Transaction state enum - represents the state of a transaction
    TransactionWriteSet
    Per-transaction buffer of pending changes — the foundation of the deferred-apply / READ COMMITTED model (see docs/acid-snowflake-plan.md).
    UpdateLog
     
    WalSink
    Callback the TransactionManager invokes when a transaction commits successfully, handing over the committed transaction's mutating SQL statements so a durability layer (the engine's write-ahead log) can append them as one atomic, fsync'd record.
    WriteSetSavepoint
    A COPY-ON-FIRST-MUTATION statement savepoint over a TransactionWriteSet.
