Distributed Database Cluster middleware

I am a distributed database cluster middleware developers, has been a little more than a year of development time, today to summarize some of the things I know, to have recently come to this field of research and development staff a little reference.

Life is not easy, making money is not easy, leaving is just for earning more money.

----School Slag

I'm just talking about the systems I've developed:

The following article will have a specific analysis. Just do a simple comb here. That is, you need to develop distributed database cluster middleware. Need to think in what way.

First we analyze the work we are doing from the name:

1. Distributed

Need to consider its direction (specify later)

A) concepts in the distributed

b) a distributed model

c) Distributed System features

2. DB Cluster

We use MySQL for back-end storage.

A) what is MySQL

b) What is the use of a database cluster (what is a sub-library table?). What is the horizontal slicing of longitudinal slices?

c) What is the role of MySQL in the system

3. Middleware

What is middleware?

The above is to infer by name what we need to know.

What technologies do we use to implement our distributed database cluster middleware?

1. Network programming required (socket, multiplexing, libevent,ace)

2. Need to have multi-threaded programming (why not multi-process, why not single thread)

3. Memory management (for operating system memory application and release, how to better manage memory)

4. Log management (how the system logs are stored.) Where to store it)

5. Metadata information Management (restart the system, can you restore to shutdown state?) ）

A lot of questions await our research. Said so much on a temporary basis. To be updated on the above issues of humble opinion.
