Is there a problem with using memcached in PHP to update data synchronously?

I think the use of memcache to pay attention to two more frequently occurring problems:

1. Update a key concurrently. (Solution: Locking)
2. After the memory partition is full, the memory block will be kicked off if it stores the new key again. (Solution: Memcache monitoring)

PHP uses memcache generally used to do a layer of MySQL data cache, to reduce the direct connection to MySQL, thereby improving performance.
The Memcache data save failed, generally because the server side of the data key already exists
In general, as long as your data key and value meet memcache conditions, and memory is enough to use, there will be little data update failure!
