Open-source in-memory databases are data storage systems meant for high-speed querying, analytics, and real-time use cases. They store data in the main memory (RAM) of a computing machine as opposed to traditional databases that use disk-based storage. This results in significantly faster read/write operations. Below are a few examples:
# To install Redis on Ubuntu sudo apt update sudo apt install redis-server
# To install Memcached on Ubuntu sudo apt update sudo apt install memcached
# To run Apache Ignite ./apache-ignite/bin/ignite.sh
// To create a new Hazelcast instance. HazelcastInstance hz = Hazelcast.newHazelcastInstance();
# To start Voltdb voltdb init voltdb start
Please note: the specifics of how you install and use these databases vary depending on the OS and specific use case. Therefore, always refer to the latest official documentation to get the most accurate information.
Dragonfly is fully compatible with the Redis ecosystem and requires no code changes to implement.
