The data of a WAL Record. This is intentionally separate to allow using the `oneof` feature in a forward-compatible way.

Used in: Record

• oneof entry_type

  The new-table entry.

  • Entry.Write write = 1

    Write is set if the entry describes a write.

  • Entry.NewTableBlock new_table_block = 2

    NewTableBlock is set if the entry describes a new-table-block.

  • Entry.TableBlockPersisted table_block_persisted = 3

    TableBlockPersisted is set if the entry describes a table-block-persisted.

  • Entry.Snapshot snapshot = 4

    Snapshot is set if the entry describes a snapshot.

The new-table-block entry.

Used in: Entry

• string table_name = 1

  Table name of the new-table-block.

• bytes block_id = 2

  Block ID of the new-table-block.

• optional table.v1alpha1.TableConfig config = 5

  Config of the new-table-block.

The snapshot entry.

Used in: Entry

• uint64 tx = 1

  The tx the snapshot was taken at.

The table-block persisted entry.

Used in: Entry

• string table_name = 1

  Table name of the new-table-block.

• bytes block_id = 2

  Block ID of the new-table-block.

• uint64 next_tx = 3

  NextTx is the next non-persisted transaction at the time of block persistence. If the block has been persisted, any txn id < next_tx is considered persisted or not relevant to this table (i.e. it can be a non-persisted txn from another table).

The write-type entry.

Used in: Entry

• string table_name = 1

  Table name of the write.

• bytes data = 2

  Data is the data of the write.

• bool arrow = 3

  Arrow indicates that data is stored in arrow record format.

Record describes a single entry into the WAL.

• optional Entry entry = 1

  Data of the record. This is intentionally nested so the only thing in the entry can be a protobuf `oneof` and have forward compatilibity.
