Redis medium
What is the primary technical mechanism by which Redis Pipelining improves throughput for bulk command operations?
- A It enables the simultaneous parallel execution of multiple commands on distinct background CPU cores.
- B It reduces Network Round Trip Time (RTT) by batching multiple commands into a single TCP packet.
- C It automatically identifies and compresses duplicate string keys before they are transmitted over the wire.
- D It implements ACID-compliant transactions by locking the primary keyspace until the entire batch finishes.
Answer: B. It reduces Network Round Trip Time (RTT) by batching multiple commands into a single TCP packet.
The bottleneck in Redis is often the network latency (Client -> Server -> Client). Pipelining packs many commands into one packet, allowing the server to process them sequentially and return all replies in one go.
One system design question a day, with spaced repetition so the ones you miss come back.
