Enum mz_persist_types::txn::TxnsEntry

pub enum TxnsEntry {
    Register(ShardId, [u8; 8]),
    Append(ShardId, [u8; 8], Vec<u8>),
}

The in-mem representation of an update in the txns shard.

Variants

Register(ShardId, [u8; 8])

A data shard register operation.

The [u8; 8] is a Codec64 encoded timestamp.

Append(ShardId, [u8; 8], Vec<u8>)

A batch written to a data shard in a txn.

The [u8; 8] is a Codec64 encoded timestamp.
