Article Introduction：HBase is a Hadoop-based distributed storage system designed to store and process large-scale structured data. In order to optimize its read and write performance, HBase provides a variety of caching mechanisms, which can improve query efficiency and reduce read and write delays through reasonable configuration. This article will introduce HBase caching technology and how to configure it. HBase cache types HBase provides two basic cache mechanisms: block cache (BlockCache) and MemStore cache (also called write cache). The block cache is in

Article Introduction：HBase writes quickly but reads slowly. The read time of HBase is usually a few milliseconds, while the read time of Redis is usually tens of microseconds. The performance difference is very big. Both HBase and Redis support KV type. But Redis supports richer types such as List and Set.

Article Introduction：The difference between HBase and Redis: 1. HBase is fast to write but slow to read. The reading time of HBase is usually a few milliseconds, while the reading time of Redis is usually tens of microseconds. The performance difference is very big. 2. Both HBase and Redis support KV type. But Redis supports richer types such as List and Set.

Article Introduction：hbase relies on "Zookeeper" to provide a message communication mechanism. ZooKeeper is a distributed, open source distributed application coordination service; as the cluster coordinator of hbase, zookeeper can coordinate and handle hbase activities.

Article Introduction：hbase relies on "HDFS" to store underlying data. HBase uses Hadoop HDFS as its file storage system to provide HBase with high-reliability underlying storage support; HDFS has high fault tolerance and is designed to be deployed on low-cost hardware.

Article Introduction：Python accesses HBase Demo. HBase is a distributed column storage system built on HDFS, mainly used for massive structured data storage. Here, our goal is only to provide a basic environment for Python to access HBase, so we directly download the binary package and install it on a single machine. After downloading, unzip it, modify the configuration file, and then start HBase directly. The system version used is ubuntu14.04.
