2.TT/TC java客户端比较弱，目前只能用memcached java client

3.Redis对并发操作提供了很多方便的API调用

4.Redis性能上比TC table要好些，跟TC B+ tree差不多

5.Redis并发处理能力要好些

我们现在使用的模式是，对于直接的key value对需缓存的直接用memcached。对于collection类型就使用Redis。对于大数据量的内容性的东西，我们打算尝试用mongoDB。也正在学习neo4j，来应对深度搜索，推荐功能。

Be patient to listen to application users to speak out their requirements. Try best to satisfy all the reasonable requirements put forward by them. Suppose and analyze their potential requirements and guide them, differentiate urgent and uncritical requirements. Put customer requirements at the first place.

耐心的倾听客户阐述他们的需求，尽量满足用户提出的所有需求，猜想并分析用户可能需要的潜在需求，引导他们。区别紧急和不重要的需求。将用户的需求放在第一位。

RESULT ORIENTATION

Strive to be complete tasks on time or ahead of its mandate, and deliver mature products

力争提前完成自己的任务，交付成熟的产品

ACHIEVEMENT DRIVE

If our outputted software solves customers’ problems, it is a sense of accomplishments to us. Software with clear architecture, good scalability, high readability and maintainability always make me feel comfortable.

写出的软件解决了客户的问题本身就是一种成就感。写出的软件架构清晰，可读性强，可维护性高也会使人开心。

TEAMWORK

Usually discussing and solving problems with team members, studying new techs and sharing with partners, Learning from each other and making progress, developing projects with my team members.

和小组成员一起讨论，研究和解决各种问题，合作开发项目，事半功倍，互相学习，不断进步。

COMMUNICATION

Firstly, I learn to be a pro-listener to understand each other’s intensions. Then, I organize my own thoughts, and speak out swimmingly in a way accepted by the other ones.

学做亲听者,了解对方的意图,换位思考, 组织好自己的想法,用对方能接受的方式畅快的表达出来.

INNOVATION

Technical innovation always happens, only through continuous research and creations, individuals are able to achieve greater efficiency to the company.

技术是不断革新的，只有通过个人的不断学习和创新才能为公司取得更大的效益。

LEADERSHIP

In the passed half year, I have pursued the implementation of rules of baselines.

在过去的半年内，曾在小组内部推行baseline的规则

PROBLEM SOLVING & DECISION MAKING

A major duty of framework developer is when there is some difficult technical problem coming out with frameworks or products, I need to respond to application user and solve the problem ASAP. Sometimes, framework developer needs to make decision on used technologies, even the whole architecture.

Framework开发者重要职责就是对用户出现技术难题的时候能够快速响应并解决。平时需要有能力对采用的技术和架构作出决定

MNAGING RELATIONSHIP

Application user is our nice customers, it is important to make a solid relationship with them. I often help my team members to solve difficult technical problems, cooperate with them to complete projects.

Application team是我们的客户，需要和他们打好关系。经常帮助小组成员解决一些技术问题，共同合作完成项目的开发。

在进入，退出方法时针对方法的输入参数和返回值进行log，log中含有方法信息

logDebugOnMethodEntry, logDebugOnMethodExit

2. log级别问题

如果log级别设置的是info，会把warning，error，fatal都打出来，各个级别不能单独控制。增加各级别分开控制开关。

3. log格式的定制

可以定制log信息的pattern，这样会看起来很统一，log分析起来也容易logDebug(String pattern, Object... paramValues);

还有一个好处，不需要预先把相关String都append起来，提高performance

4. log.isDebugEnabled();

参考第三点，这样就避免了Object的toString和String的concat操作。

5. EmptyLogger

每次记log时，log4j都需要判断这个级别是否可以打log。如果logger的每个级别都有对应的logger实例，如果debug level被关了，debug级别对应的实例就是EmptyLogger，EmptyLogger里面所有方法的实现都是空的，就不需要这额外的判断了。

Java, Java, Java Java jing-jing-jing
Java, Java, Java Java jing-jing-jing

It's not a cup of coffee but it's hot as can be
Came pourin' through the Gates on a "Big Mac" Nealy
Singin', Java, Java, Java Java jing-jing-jing

Microsoft thought Java really could be a threat
Java through the Windows maybe put them in debt
Gates, he took a license but he altered the feel
Java members all said, "Bill, you're outa the deal!"

Singin', Java, Java, Java Java jing-jing-jing
Java, Java, Java Java jing-jing-jing

It's like a cup of coffee 'cause it's tasty and fresh
But it's not really Java if the flavors don't mesh
Pure Java, Java, Java Java jing-jing-jing

Microsoft released a browser, Java was there
The Sun, it rose and lit up what was really a dare
The RMI, the JNI were missing and lost
Scott said, "Bill, you broke your promise, Now pay the cost!"

Bill said, "Hey, my recipe is richer than yours"
Scott said, "I own the coffee shop, sit down and I'll pour"

Pour Java, Java, Java Java jing-jing-jing
Java, Java, Java Java jing-jing-jing
Nobody can tell yet what the future may bring
All we know is Java goes jing-jing-jing

It goes Java, Java, Java Java jing-jing-jing
(Scott really means it)
Java, Java, Java Java jing-jing-jing
(Bill you better believe it)
Java, Java Java jing-jing-jing
