pub struct TxnIdGenerator {
worker_id: u32,
sequence: AtomicU32,
}Expand description
TxnIdGenerator generates unique transaction ids as following format:
| worker id | sequence |
|---|---|
| 32 bits | 32 bits |
Currently, we just need to guarantee the transaction ids are unique at runtime. It doesn’t matter, even if the sequence starts from zero after recovery.
