## 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):
|
|
```python
|
|
# 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):
|
|
```java
|
|
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):
|
|
```python
|
|
# Bad: N round trips
|
|
results = []
|
|
for user_id in user_ids:
|
|
results.append(redis.get(f"user:{user_id}"))
|
|
```
|
|
|
|
**Java** (Jedis):
|
|
```java
|
|
// Bad: 3 separate round trips
|
|
jedis.set("person:1:name", "Alex");
|
|
jedis.set("person:1:rank", "Captain");
|
|
jedis.set("person:1:serial", "AB1234");
|
|
```
