MyTable

Yet another NoSql database based on leveldb.

Features

• Simple, small code base, easy to learn API
• Very fast, high performance

Simple tutorial

####1. Start MyTable server

com.lubin.myTable.server.MyTableServer

####2. Create a client and try basic operation...

IMyTableclient = MyTableClient.getInstance();
Stringkey = "hello";
client.put(key, bytes("myTable"));
byte[] value = client.get(key);
System.out.println("key="+key+"	value=" + asString(value)+"\n");
client.delete(key);
client.put("a", bytes("myTable:"+ "a"));
client.put("b", bytes("myTable:"+ "b"));
client.put("c", bytes("myTable:"+ "c"));
client.put("d", bytes("myTable:"+ "d"));
client.put("e", bytes("myTable:"+ "e"));
Map<String, byte[]> res = client.range("a", "d");
for(Map.Entry<String, byte[]> entry :res.entrySet()){
System.out.println("key="+entry.getKey() + "	value="+asString(entry.getValue()));
}

output:

key=hello	value=myTable
key=a	value=myTable:a
key=b	value=myTable:b
key=c	value=myTable:c

####3. Config file for myTable server

server{port=9090backlog=1000async=false//handling request in business logic thread poolasyncThreadPoolSize=4ioThreadNum=1objects=[com.lubin.myTable.obj.MyTableObj]}leveldb{dataDir="default"createIfMissing=truecacheSize=500//500MwriteBufferSize=16//16MWriteOptions{sync=false}ReadOptions{fillCache=trueverifyChecksums=true}}

####4. Config file for myTable client

client{reconnInterval=1000//time interval(million second) for reconnecting to serverasyncThreadPoolSize=1//thread pool for excuting Async callbackioThreadNum=2serializer=0//0 kryo 1 jsonobjects=[{ name =com.lubin.myTable.obj.IMyTableservers="127.0.0.1:9090"}]}

Build

To build the JAR file of myTable, you need to install Maven (http://maven.apache.org), then type the following command:

$ mvn package

To generate project files (.project, .classpath) for Eclipse, do

$ mvn eclipse:eclipse

then import the folder from your Eclipse.
