编程小梦|Google Mesa 论文解读

  1. Atomic Updates.
  2. Consistency and Correctness.
  3. Availability: 永不停服，无论是预期内还是预期外的，并可以接受一个数据中心完全down掉。
  4. Near Real-Time Update Throughput: 近实时的高吞吐更新。数据摄入时不仅支持追加新数据也支持更新已有数据。
  5. Query Performance： 同时支持数百毫秒低延迟的点查询和高吞吐的批量查询。
  6. Scalability： 数据摄入和查询性能可以随集群规模线性增长。
  7. Online Data and Metadata Transformation：在线的表Schema变更，表的Schema变更不会影响数据的摄入和查询。
