Integrate MongoDB with Apache Spark using the MongoDB Connector for Spark, supporting Spark Structured Streaming.
③ Mongo-spark数据分析通过错峰实现,统一凌晨实现。 数据库场景非常重要,脱离业务场景谈数据库优劣无任何意义。例如本文的业务场景,业务能确定需要建那些索引,同时所有的更新、查询、排序都可以对应具体的最优索引,因此该场景就非常适合MongoDB。 每种数据库都有其适合的业务场景,没有万能的数据库。此外,不能因为某种...
MongoDB作为Spark的存储方案,MongoDB相比HDFS更加细粒度存储,并且支持结构化存储。MongoDB支持索引机制,使得Spark的读取更加快速,HDFS是一次写,多次读,但是MongoDB适合Spark的读写混合场景。MongoDB是在线式存储,毫秒级的SLA。 (4)可视化与ETL MongoDB可以通过BI Connector实现与SQL的结合。BI Connector会自动产生DRDL映...
