What is difference between Memcached and Redis?

When storing data, Redis stores data as specific data types, whereas Memcached only stores data as strings. Because of this, Redis can change data in place without having to re-upload the entire data value. This reduces network overhead. Below I cover the different types of data that Redis can handle.

Can I use both Redis and Memcached?

The sub-millisecond latency/response time is supported by both Redis and Memcached. So as the data is stored in memory, the data can be read more quickly than the databases based on disk. Redis has more features than Memcached and is, thus, more powerful and flexible.

When should you not use memcache?

You have objects larger than 1MB. Memcached is not for large media and streaming huge blobs….4 Answers

  1. You have keys larger than 250 chars.
  2. Your hosting provider won’t let you run memcached.
  3. You’re running in an insecure environment.
  4. You want persistence.

Who created memcache?

Brad Fitzpatrick
Memcached was first developed by Brad Fitzpatrick for his website LiveJournal, on May 22, 2003. It was originally written in Perl, then later rewritten in C by Anatoly Vorobey, then employed by LiveJournal.

What is the default memory pool of Memached?

For example, the default allocation of memory to memcached on a web server is 64M.

What is the difference between Redis and Kafka?

It is extremely fast one can use it for caching session management, high-performance database and a message broker. In terms of storage and multiple functionalities, Redis is a bit different from Kafka….Redis vs Kafka Comparison Table.

Comparison Points Redis Kafka
Speed Faster Not as fast as Redis

Is Redis and Kafka same?

Kafka is an Enterprise Messaging Framework whereas Redis is an Enterprise Cache Broker, in-memory database and high performance database. Both are having their own advantages, but they are different in usage and implementation.

What are the differences between Redis and Memcached?

redis persists the entire dataset to disk

  • redis doesn’t support LRU or any similar policy for handling overload
  • redis doesn’t support CAS (check and set) which is useful for maintaining cache consistency – see What are the most common sources of memcached cache inconsistency?

    • Is Redis a good alternative to Memcache?

    MongoDB. MongoDB is a document-oriented storage platform allowing users to store objects in JSON like documents rather than tables that vary in structure thus offering a dynamic and flexible

  • Memcached. It is a high-performance cache framework for distributed memory objects.
  • Hazelcast.
  • Apache Cassandra.
  • CouchBase.
  • ElasticSearch.
  • Kafka.
  • RabbitMQ.
  • DynamoDB.

    • What are the advantages of using Memcache over Redis?

    Direct access to the InnoDB storage engine avoids the parsing and planning overhead of SQL.

  • Running memcached in the same process space as the MySQL server avoids the network overhead of passing requests back and forth.
  • Data written using the memcached protocol is transparently written to an InnoDB table,without going through the MySQL SQL layer.

    • How do you choose between Memcached, Redis and varnish?

    No longer need to perform management tasks such as hardware provisioning,software patching,setup,configuration,and failure recovery.

  • Have access to monitoring metrics associated with your nodes,enabling you to diagnose and react to issues quickly.
  • Can take advantage of cost-efficient and resizable hardware capacity.
