Use Pipelining for Bulk Operations
Batch multiple commands into a single round trip to reduce network latency.
Correct: Use pipeline for multiple commands.
Python (redis-py):
# Good: Single round trip for multiple commands
pipe = redis.pipeline()
for user_id in user_ids:
pipe.get(f"user:{user_id}")
results = pipe.execute()
Java (Jedis):
import redis.clients.jedis.Pipeline;
// Good: Buffer commands and send as single batch
Pipeline pipe = (Pipeline) jedis.pipelined();
pipe.set("person:1:name", "Alex");
pipe.set("person:1:rank", "Captain");
pipe.set("person:1:serial", "AB1234");
pipe.sync();
Incorrect: Sequential commands in a loop.
Python (redis-py):
# Bad: N round trips
results = []
for user_id in user_ids:
results.append(redis.get(f"user:{user_id}"))
Java (Jedis):
// Bad: 3 separate round trips
jedis.set("person:1:name", "Alex");
jedis.set("person:1:rank", "Captain");
jedis.set("person:1:serial", "AB1234");
