), my personal direction is actually big data/distributed computing, but big data too much to use in Java, So Java also learned well: d[1] laying the groundwork (with a problem when learning) (1) Language: Solid to play a good Java Foundation, focus on the concurrency and network parts, understand some common design patterns (do not back, need experience to understand).

projects to gain experience. The problem with MySQL and time series data sharding (fragmentation) is that there is always a slice too hot. In addition, the problem of read replication latency is encountered because you want to insert concurrency on slave. In addition, a common service framework has been developed: It takes a lot of time to solve the operational dimension of distributed system Management. A rails scaffolding is developed for the service, and the internal template is used to star

Recently, when processing data, you need to join the raw data with Redis data, in the process of reading Redis, encountered some problems, by the way to make a note, hoping for other students also helpful. During the experiment, it was not stressful to read Redis one at a time when the amount of data was 100,000 levels, but when the amount of data reached tens, the problem arose, even with the mappartitions of Spark. Therefore, consider using Redis's pipeline (if you have a better approach, plea
