Flink minibatch
Web主题:Elasticsearch mini batch loader - 流批一体的海量索引外部构建方案 简介: ES在字节跳动有着大规模的使用。为了应对实时数据的快速增长、提供极高的写入性能、降低读写资源竞争,我们基于Flink实现了在ES集群之外以mini batch的方式构建索引并传输至ES集群的方案,单节点写入速度达到每秒近百万 ... Web二、开启 MiniBatch. MiniBatch 是微批处理,原理是缓存一定的数据后再触发处理,以减少对 State 的访问,从而提升吞吐并减少数据的输出量。MiniBatch 主要依靠在每个 Task 上注册的 Timer 线程来触发微批,需要消耗一定的线程调度性能。 MiniBatch 默认关闭,开启方 …
