Class topic

1. Introduction to HBase

This post describes the non-relational distributed database called HBase in the Hadoop open-source community, which can meet the requirements of large-scale and real-time data processing applications...(More)

2. Introduction to MapReduce

This post describes MapReduce. MapReduce is the most famous computing framework for batch processing and offline processing in the big data field. In this post, you will learn its principles, processes, and application scenarios...(More)

3. Introduction to Flink

Apache Flink is an open-source stream processing framework for distributed, high-performance stream processing applications. Flink not only supports real-time computing with both high throughput and exactly-once semantics but also provides batch data processing...(More)

4. HCIA-Big Data | Flink Time & Window

In-stream processor programming, time processing is very critical. For example, event stream data (such as server log data, web page click data, and transaction data) is continuously generated. In this case, you need to use keys to group events and count the events corresponding to each key at a specified interval. This is our known "big data" application...(More)

5. HBase Key Processes and Highlights

HBase is a distributed, column-oriented storage system built on the Hadoop Distributed File System (HDFS). The column-based HBase features high reliability, performance, and scalability. HBase is suitable for storing big table data (a table containing billions of rows and millions of columns) and allows real-time data access...(More)
