1.减轻：
Weaviate是基于GraphQL的开源智能图，具有以下核心功能：语义搜索，自动分类和知识表示。主数据库模型是Search Engine，辅助数据库模型是Graph DBMS。它允许我们的数据基于GraphQL查询语言以大图形格式表示。它的搜索图基于称为Contextionary的图嵌入机制。
2. VoltDB：
VoltDB是分布式内存NewSQL RDBMS和使用无共享体系结构的ACID兼容RDBMS。该数据库由Michael Stonebraker，Sam Madden和Daniel Abadi设计。最初，VoltDB数据库包括群集吞吐量和延迟以及CPU和内存使用情况的图表。 VoltDB基于H-Store，并随着多核服务器上每CPU核心数的增加而扩展。
