Zero partial writes: Atomic transactions and rollback guarantees.

Zero partial writes: Atomic transactions and rollback guarantees.

A sudden network drop or unhandled exception mid-operation can corrupt your local database forever. wsqlite's transaction context managers guarantee atomic all-or-nothing execution in both sync and async modes.

Here is how you use Atomic Transactions & Context Managers in production with wsqlite:

from wsqlite.core.connection import get_transaction

# Atomic multi-table transfer
with get_transaction("bank.db") as tx:
    # 1. Deduct from account A
    tx.execute("UPDATE accounts SET balance = balance - 100 WHERE id = 1")

    # 2. Add to account B
    tx.execute("UPDATE accounts SET balance = balance + 100 WHERE id = 2")

    # If any error occurs here, BOTH statements roll back automatically!
# Auto-committed cleanly on exit of the 'with' block
Enter fullscreen mode Exit fullscreen mode

Why developers love wsqlite:

  • Define database tables using standard Pydantic v2 models.
  • Auto-syncs columns on startup without writing manual migrations.
  • Thread-safe connection pooling with WAL mode enabled by default (5,000+ inserts/sec).
  • Full sync and async/await support.

Check out the repo on GitHub!
