Transactions

Barq changes happen inside write transactions.

Reads can happen outside a write. Creates, updates, and deletes must be inside a write.

JavaScript

barq.write(() => {
  const task = barq.create(Task, {
    _id: new Barq.Types.ObjectId(),
    description: 'Write docs',
  });

  task.done = true;
});

C++

auto managed = database.write([&] {
    return database.add(Dog{.name = "Rex", .age = 1});
});

Keep Writes Small

Do only the needed data changes inside a write block.

Avoid slow network calls, long CPU work, or user prompts inside a write transaction.
