Summary: [GSoC] RocketMQ TieredStore Integration with HDFS
Key: COMDEV-506
URL: https://issues.apache.org/jira/browse/COMDEV-506
Project: Community Development
Issue Type: New Feature
Environment: rocketmq,hdfs
Reporter: Zhimin Li
h2. [GSoC] RocketMQ TieredStore Integration with HDFS
Github Issue: [https://github.com/apache/rocketmq/issues/6282]
h3. Apache RocketMQ and HDFS
* Apache RocketMQ is a cloud native messaging and streaming platform, making
it simple to build event-driven applications.
* Hadoop Distributed File System (HDFS) is a distributed file system designed
to store and manage large data sets across multiple servers or clusters. HDFS
provides a reliable, scalable, and fault-tolerant platform for storing and
accessing data that can be accessed by a variety of applications running on the
hadoop cluster.
h3. Background
High-speed storage media, such as solid-state drives (SSDs), are typically more
expensive than traditional hard disk drives (HDDs). To minimize storage costs,
the local data disk size of a rocketmq broker is often limited. HDFS can store
large amounts of data at a lower cost, it has better support for storing and
retrieving data sequentially rather than randomly. In order to preserve message
data over a long period or facilitate message export, the RocketMQ project
previously introduced a tiered storage plugin. Now it is necessary to implement
a storage plugin to save data on hdfs.
h3. Relevant Skills
* Interest in messging middleware and distributed storage system
* Java development skills
* Having a good understanding of rocketmq and hdfs models
Anyways, the most important relevant skill is motivation and readiness to learn
during the project!
h3. Tasks
* understand the basic concepts and principles in distributed systems
* provide related design documents
* develop one that uses hdfs as the backend storage plugin to store rocketmq
message data
* write effective unit test code
* *suggest improvements to the tiered storage interface
* *what ever comes in your mind further ideas are always welcome
