MPI是一个库,而不是一门语言。
CockroachDB
is a distributed SQL database. The primary design goals are scalability, strong consistency and survivability (hence the name). CockroachDB aims to tolerate disk, machine, rack, and even datacenter failures with minimal latency disruption and no manual intervention. CockroachDB nodes are symmetric; a design goal is homogeneous deployment (one binary) with minimal configuration and no required external dependencies.

Apache Calcite
希望能为不同计算平台和数据源提供统一的查询引擎,并以类似传统数据库的访问方式来访问 Hadoop 上的数据。除此之外,Calcite
还提供了 OLAP 和流处理的查询引擎。
