Is Memcached distributed cache?
Memcached (pronounced variously mem-cash-dee or mem-cashed) is a general-purpose distributed memory-caching system. It is often used to speed up dynamic database-driven websites by caching data and objects in RAM to reduce the number of times an external data source (such as a database or API) must be read.
Does memcached use UDP?
By default, memcached exposes UDP 11211. With the specs of the protocol being what they are, this is one of the best protocols to use for amplified attacks ever as a 15 byte request can trigger a 750k response to a user defined, spoofed IP address, resulting in a 51,200x amplification factor.
What is Memcached and what does it do?
Memcached is an in-memory key-value store for small chunks of arbitrary data (strings, objects) from results of database calls, API calls, or page rendering. Memcached is simple yet powerful. Its simple design promotes quick deployment, ease of development, and solves many problems facing large data caches.
How is memory cache used in App Engine?
High performance scalable web applications often use a distributed in-memory data cache in front of or in place of robust persistent storage for some tasks. App Engine includes a memory cache service for this purpose. To learn how to configure, monitor, and use the memcache service, read Using Memcache.
When to use Memcache for datastore queries?
If many requests make the same query with the same parameters, and changes to the results do not need to appear on the web site right away, the application can cache the results in the memcache. Subsequent requests can check the memcache, and only perform the datastore query if the results are absent or expired.
How much traffic can I expect from Memcache?
You can roughly associate a cost with operations and estimate the traffic capacity that you can expect from dedicated memcache using a unit called Memcache Compute Unit (MCU). MCU is defined such that you can expect 10,000 MCU per second per GB of dedicated memcache. The Google Cloud Console shows how much MCU your app is currently using.
