這篇文章給大家介紹Java中protobuf與avro的區別是什么，內容非常詳細，感興趣的小伙伴們可以參考借鑒，希望對大家能有所幫助。
一、protobuf基本操作
protobuf簡介：
Protocol Buffers (a.k.a., protobuf) are Google's language-neutral, platform-neutral, extensible mechanism for serializing structured data.
protobuf是google提供的一種跨語言、跨平臺、可擴展的序列化工具。
1.1定義協議文件(部分字段)(TCPLog.proto)：
syntax = "proto2";
message TCPLog{
optional int32 total_byteps = 1;
optional int64 flow_start_time =2;
optional int64 date =3;
}1.2生成對應的Java類：
生成過程可以使用ecplise 的插件 或者 直接在控制臺中使用命令生成。
命令行中生成規則如下：
protoc.exe -I=proto的輸入目錄 --java_out=java類輸出目錄 proto的輸入目錄包括包括proto文件
生成java類如下：
// Generated by the protocol buffer compiler. DO NOT EDIT!
// source: TCPLog.proto
public final class TCPLogOuterClass {
private TCPLogOuterClass() {}
public static void registerAllExtensions(
com.google.protobuf.ExtensionRegistryLite registry) {
}
public static void registerAllExtensions(
com.google.protobuf.ExtensionRegistry registry) {
registerAllExtensions(
(com.google.protobuf.ExtensionRegistryLite) registry);
}

}之后便可以使用該類進行序列化和反序列化。
具體示例代碼如下》：
import java.io.File;
import java.io.FileOutputStream;
public class ProtoTest3 {
/**
* @param args
* @throws Exception
* @author qiang(upupgo)
*/
public static void main(String[] args) throws Exception {
//模擬將對象轉成byte[]，方便傳輸
TCPLogOuterClass.TCPLog.Builder builder = TCPLogOuterClass.TCPLog.newBuilder();
builder.setTotalByteps(1024);
builder.setFlowStartTime(1502415717l);
builder.setDate(1502415717l);
//序列化到文件
TCPLogOuterClass.TCPLog tcpLog= builder.build();
FileOutputStream out = new FileOutputStream(new File("D:/pb"));
out.write(tcpLog.toByteArray());
out.close();
//反序列化
TCPLogOuterClass.TCPLog tcp = TCPLogOuterClass.TCPLog.parseFrom(tcpLog.toByteArray());
System.out.println(tcp);
}
}二、AVRO序列化基本操作：
AVRO簡介：
Apache Avro? is a data serialization system. Avro provides: Rich data structures. A compact, fast, binary data format. A container file, to store persistent data. Remote procedure call (RPC). Simple integration with dynamic languages. Code generation is not required to read or write data files nor to use or implement RPC protocols. Code generation as an optional optimization, only worth implementing for statically typed languages.
Avro是一個序列化系統。豐富的數據結構、快速壓縮的二進制數據格式、數據持久化存儲、RPC及動態語言集成。
2.1定義協議文件(TCPLog.avro)
{"namespace": "example.avro",
"type": "record",
"name": "TCPLog",
"fields": [
{"name": "total_byteps", "type": "int"},
{"name": "flow_start_time", "type": "long"},
{"name": "date", "type": "long"}
]
}avro和protobuf一樣可以生成相應語言的類文件，或直接支持動態擴張。下面以Java語言不生成類說明：
具體序列化與反序列化操作代碼如下：、
package avro;
import java.io.File;
import org.apache.avro.Schema;
import org.apache.avro.file.DataFileReader;
import org.apache.avro.file.DataFileWriter;

import org.apache.avro.io.DatumWriter;

}以下是通過對100W tcpLog序列化操作對比結論：
通過對比測試發現 avro的性能要不pb稍微好一些，且支持動態性。故技術選型上可以優先考慮。
以上是通過測試對比了pb與avro的一些性能差異，但是具體測試和機器和樣本都有關系，可以參考。
以下是對比protobuf、avro、thrift的一些優缺點：
Google protobuf： 優點 二進制消息，性能好/效率高（空間和時間效率都很不錯） proto文件生成目標代碼，簡單易用 序列化反序列化直接對應程序中的數據類，不需要解析后在進行映射(XML,JSON都是這種方式) 支持向前兼容（新加字段采用默認值）和向后兼容（忽略新加字段），簡化升級 支持多種語言（可以把proto文件看做IDL文件） Netty等一些框架集成 缺點 官方只支持C++,JAVA和Python語言綁定 二進制可讀性差（貌似提供了Text_Fromat功能） 二進制不具有自描述特性 默認不具備動態特性（可以通過動態定義生成消息類型或者動態編譯支持） 只涉及序列化和反序列化技術，不涉及RPC功能（類似XML或者JSON的解析器） Apache Thrift： 應用 Facebook的開源的日志收集系統(scribe: https://github.com/facebook/scribe) 淘寶的實時數據傳輸平臺(TimeTunnel http://code.taobao.org/p/TimeTunnel/wiki/index) Evernote開放接口(https://github.com/evernote/evernote-thrift) Quora(http://www.quora.com/Apache-Thrift) HBase( http://abloz.com/hbase/book.html#thrift ) … 優點 支持非常多的語言綁定 thrift文件生成目標代碼，簡單易用 消息定義文件支持注釋 數據結構與傳輸表現的分離，支持多種消息格式 包含完整的客戶端/服務端堆棧，可快速實現RPC 支持同步和異步通信 缺點 和protobuf一樣不支持動態特性 Apache Avro： 應用 Hadoop RPC （http://hadoop.apache.org/#What+Is+Apache+Hadoop%3F） 優點 二進制消息，性能好/效率高 使用JSON描述模式 模式和數據統一存儲，消息自描述，不需要生成stub代碼（支持生成IDL） RPC調用在握手階段交換模式定義 包含完整的客戶端/服務端堆棧，可快速實現RPC 支持同步和異步通信 支持動態消息 模式定義允許定義數據的排序（序列化時會遵循這個順序） 提供了基于Jetty內核的服務基于Netty的服務 缺點 只支持Avro自己的序列化格式 語言綁定不如Thrift豐富
