Difference between Weaviate and VoltDB
  • Last Updated : 27 Jul, 2020

1. Weaviate :
Weaviate is an open-source GraphQL-based Smart Graph with the core features: semantic search, automatic classification, and knowledge representation. Primary database model is Search Engine and secondary database models is Graph DBMS. It allows our data to represent in a large graph format based on the GraphQL query language. Its search graph based on a graph embedding mechanism called the Contextionary.

2. VoltDB :
VoltDB is distributed In-Memory NewSQL RDBMS and an ACID-compliant RDBMS that uses a shared nothing architecture. This database designed by Michael Stonebraker, Sam Madden, and Daniel Abadi. Initially VoltDB database includes graphs for cluster throughput and latency as well as CPU and memory usage. VoltDB is based on H-Store and scales with the increasing core-per-CPU counts on multi-core servers.
