Scylla vs OrbitDB: What are the differences?
Developers describe Scylla as "Next Generation Cassandra". Real-time big data database, with scale-up performance of 1,000,000 IOPS per node, scale-out to 100s of nodes and 99 latency of less than 1 msec. On the other hand, OrbitDB is detailed as "Peer-to-Peer Databases for the Decentralized Web". It is a serverless, distributed, peer-to-peer database. It uses IPFS as its data storage and IPFS Pubsub to automatically sync databases with peers. It’s an eventually consistent database that uses CRDTs for conflict-free database merges making it an excellent choice for decentralized apps (dApps), blockchain applications and offline-first web applications.
Scylla and OrbitDB can be categorized as "Databases" tools.
