ClustrixDB vs Scylla: What are the differences?
# Introduction
Key differences between ClustrixDB and Scylla:
1. **Architecture**: ClustrixDB is a shared-nothing architecture where data is distributed across multiple nodes, whereas Scylla is a shared-nothing architecture with a masterless design.
2. **Consistency**: ClustrixDB provides strong consistency, while Scylla offers eventual consistency.
3. **Data Model**: ClustrixDB uses a relational data model with SQL support, while Scylla uses a NoSQL data model with CQL (Cassandra Query Language) support.
4. **Scaling**: ClustrixDB can scale both horizontally and vertically, while Scylla is designed for horizontal scaling.
5. **Storage Engine**: ClustrixDB uses a distributed shared-nothing architecture, whereas Scylla uses an LSM (Log-Structured Merge) tree-based storage engine.
6. **Indexing**: ClustrixDB uses traditional B-tree indexes, while Scylla utilizes SSTable-based indexes for efficient data retrieval.
In Summary, the key differences between ClustrixDB and Scylla lie in their architecture, consistency model, data model, scaling capabilities, storage engine, and indexing methods.
