## Configure Connection Timeouts
|
|
|
|
Configure appropriate timeout values to improve your application's connection resilience. While most Redis clients set default timeouts, choosing well-tuned values based on your application's usage patterns leads to better failure recovery.
|
|
|
|
**Correct:** Set timeouts based on your application needs.
|
|
|
|
```python
|
|
r = redis.Redis(
|
|
host='localhost',
|
|
socket_timeout=5.0, # Read/write timeout - tune based on expected operation time
|
|
socket_connect_timeout=2.0, # Connection timeout - shorter for fast failure detection
|
|
retry_on_timeout=True # Automatic retry on timeout
|
|
)
|
|
```
|
|
|
|
**Incorrect:** Relying solely on defaults without considering your use case.
|
|
|
|
```python
|
|
# Not ideal: Default timeouts may not match your application's needs
|
|
r = redis.Redis(host='localhost')
|
|
|
|
# For example, if your app needs fast failure detection,
|
|
# the default timeouts might be too generous
|
|
```
|
|
|
|
**Considerations:**
|
|
- Set `socket_connect_timeout` shorter than `socket_timeout` for quick connection failure detection
|
|
- For latency-sensitive apps, use tighter timeouts with retry logic
|
|
- For batch operations, allow longer timeouts to complete large operations
|
|
- Consider using health checks alongside timeouts for robust failure handling
|
