Cassandra Practice Test

In Cassandra, what is the structure of a batch write operation?

1. All statements must be written sequentially

2. All statements can run simultaneously without order

3. It is limited to only one table

4. It must include a read operation

The correct answer is: All statements can run simultaneously without order

The correct answer indicates that all statements in a batch write operation can run simultaneously without a specific order. In Cassandra, batch operations allow for the grouping of multiple write statements that can be executed together, significantly improving efficiency. This is especially beneficial for scenarios where performance is critical, as it reduces the overhead of individual write requests. Cassandra's design allows for simultaneous execution of batched writes to improve throughput and reduce latency. However, it's essential to understand that while the statements can be part of a single batch operation, they do not necessarily need to be executed in any specific sequence, emphasizing the system's distributed nature. The other choices present more restrictive conditions that do not align with Cassandra's batch processing capabilities. The platform is designed for high availability and scalability, allowing flexible batch operations that are integral to its performance.
