Redis Alternative for App Performance | Gigaspaces
Redis offers a RESTful API for accessing data stored within its in-memory technology data structures. This API provides a simple and efficient way to interact with Redis, enabling developers to leverage its capabilities seamlessly in their applications. Developers also need to manage the Redis cached data lifecycle, it’s the application responsibility to store the data & check whether it’s available in the cache....
Are Free, Open-Source Message Queues Right For You?
A notable challenge with Redis Streams is that it doesn't natively support distributed, horizontal scaling. Also, while Redis is famous for its speed and simplicity, managing and scaling a Redis installation may be complex for some users, particularly for persistent data workloads.
Redis vs. KeyDB vs. Dragonfly vs. Skytable | Hacker News
1. Redis: I'll start with Redis which I'd like to call the "original" key/value store (after memcached) because it is the oldest and most widely used of all. Being a long-time follower of Redis, I do know it's single-threaded (and uses io-threads since 6.0) and hence it achieves lesser throughput than the other stores listed above which are multi-threaded, at least to some extent. The best parts about Redis: it's...
Memcached vs Redis - More Different Than You Would Expect
Remember when I wrote about how Redis was using malloc to assign memory? I lied. While Redis did use malloc at some point, these days Redis actually uses jemalloc. The reason for this is that jemalloc, while having lower peak performance has lower memory fragmentation helping to solve the framented memory issues that Redis experiences.
Top 15 Kafka Alternatives Popular In 2021
Redis is a known, open-source, in-memory data structure store that offers different data structures like lists, strings, hashes, sets, bitmaps, streams, geospatial indexes, etc. It is best utilized as a cache, memory broker, and cache. It has optional durability and inbuilt replication potential. It offers a great deal of availability through Redis Sentinel and Redis Cluster.
Comparing the new Redis6 multithreaded I/O to Elasticache & KeyDB
So there are 3 offerings by 3 companies, all compatible with eachother and based off open source Redis: Elasticache is offered as an optimized service offering of Redis; RedisLabs and Redis providing a core product and monetized offering, and KeyDB which remains a fast cutting edge (open source) superset of Redis. This blog looks specifically at performance, however there is a section at the end of this blog that...
When to use Aerospike vs Redis | Aerospike
Need for strong data consistency If companies are building mission-critical applications where data consistency is a must, then Redis is not likely the right choice. Redis has not passed the Jepsen test for strong consistency (whereas Aerospike has). Redis supports eventual consistency, which can result in stale reads and even data loss under certain circumstances. Redis has released a WAIT command, which is most...
HazelCast - Redis Replacement
High availability of Redis is provided by Redis Sentinel, which continuously monitors the Redis cluster and initiates a slave promotion if it detects a master failure. At least three instances of Sentinel are recommended for a reliable deployment, which unnecessarily uses resources.
KeyDB: A Multithreaded Redis Fork | Hacker News
"Well, thatâs the plan: I/O threading is not going to happen in Redis AFAIK, because after much consideration I think itâs a lot of complexity without a good reason. Many Redis setups are network or memory bound actually. Additionally I really believe in a share-nothing setup, so the way I want to scale Redis is by improving the support for multiple Redis instances to be executed in the same host, especially...
20+ MongoDB Alternatives You Should Know About
Redis is another contender for some MongoDB workloads. Often used as a cache in front of MongoDB, it can also be used as a JSON store through extensions. While such extensions from RedisLabs are no longer open source, GoodForm projects provides open source alternatives.
Redis vs. Memcached: In-Memory Data Storage Systems
Redis’ RDB file is, to an extent, incorruptible because it performs its write operations in a new process. Upon the generation of a new RDB file, the Redis-generated subprocess will first write the data into a temporary file, and then rename the temporary file into a RDB file through the atomic rename system call, so that the RDB file is always available whenever Redis suffers a fault. At the same time, the Redis’...
Migrate from Redis to SSDB
If you want to delete a hash entirely, you have to use a SSDB client to execute hclear command. You cannot delete a hash with any Redis client.
