Micro is a standard library for microservices.
|
|
|
|
## Overview
|
|
|
|
Micro provides the core requirements for distributed systems development including RPC and Event driven communication.
|
|
|
|
## Features
|
|
|
|
Micro abstracts away the details of distributed systems. Here are the main features.
|
|
|
|
- **Dynamic Config** - Load and hot reload dynamic config from anywhere. The config interface provides a way to load application
|
|
level config from any source such as env vars, cmdline, file, consul, vault... You can merge the sources and even define fallbacks.
|
|
|
|
- **Data Storage** - A simple data store interface to read, write and delete records. It includes support for memory, file and
|
|
s3. State and persistence becomes a core requirement beyond prototyping and Micro looks to build that into the framework.
|
|
|
|
- **Service Discovery** - Automatic service registration and name resolution. Service discovery is at the core of micro service
|
|
development. When service A needs to speak to service B it needs the location of that service.
|
|
|
|
- **Message Encoding** - Dynamic message encoding based on content-type. The client and server will use codecs along with content-type
|
|
to seamlessly encode and decode Go types for you. Any variety of messages could be encoded and sent from different clients. The client
|
|
and server handle this by default.
|
|
|
|
- **Async Messaging** - Pub/Sub is built in as a first class citizen for asynchronous communication and event driven architectures.
|
|
Event notifications are a core pattern in micro service development.
|
|
|
|
- **Synchronization** - Distributed systems are often built in an eventually consistent manner. Support for distributed locking and
|
|
leadership are built in as a Sync interface. When using an eventually consistent database or scheduling use the Sync interface.
|
|
|
|
- **Pluggable Interfaces** - Micro makes use of Go interfaces for each system abstraction. Because of this these interfaces
|
|
are pluggable and allows Micro to be runtime agnostic.
