apache pinot 是一个很不错的olap 服务，功能强大，低延迟，包含了实时以及离线处理
支持的特性
- 非常快（支持离线以及实时处理）
- 水平扩展（基于了apache helix 框架）
- 插件化索引，包含sorted index，bitmap index,invertes index, startree index , bloom filter,range index, 文本检索，json index，geo index
- 近实时的数据进入（kafka，pulsar）
- 类sql 查询
- 基于prestodb，trino，进行多表查询（主要是当前不支持，只能基于此处理，当然dremio也是一种选择，但是肯定没有官方推荐的好）
- 异常分析，只能报警，主要基于了thirdeye
