It's about to start planning and learning the system.

I haven't written a blog for a long time. This is a long period of time with many chores and many work tasks. A large amount of time is spent in meetings every day, and people are constantly interrupted by ongoing tasks. But always learn to adapt, no way, life is like this.
There are many things to learn, many of which are unfamiliar. I really need to plan the learning method well. I plan to complete a new learning method every one to two weeks. If something new appears during this time, it will be arranged in the Learning list, use FIFO mode.
Preliminary plan:
1. Rest thinking
2. MySQL NDB
3. pgsql
4. Distributed File System
