Search for "Inmon and Kimball" on Google, and you'll easily find the concepts of these two names, which are two of the best-known ways of data Warehouse architecture. In this ocean of information, however, you will find that almost all of the content can come to a conclusion, that is, to choose between Bill Inmon and Ralph Kimball. But the "Father of Data Wareho

: Responsible for accepting tasks assigned by Nimbus, starting and stopping worker processes that belong to their own management. Worker: A process that runs a specific processing component logic. Spout: The component that produces the source data stream in a topology. Bolt: A component that accepts data in a topology and then executes the processing. Each Spout/bolt thread in the Task:worke

Problem IntroductionUsing storm, you can easily build a clustered data framework and implement business logic by defining topo.But with Topo there is a disadvantage that Topo's processing power comes from the number of workers they set up at startup, and in many cases we need to be able to adjust the processing power of the cluster based on business pressure, when a single topo cannot solve the problem.In order to be able to define the processing abil

With the rapid growth of data, sub-tables, sub-Libraries, memcache,redis,mongodb,hadoop,bigtable, and so on, a variety of solutions. After testing, in MySQL, regardless of index, data over hundred W, the query time is obvious.So MySQL sub-table sub-Library +memcache+redis is also a perfect solution.Because Redis does not support complex queries, the read performance of Redis is still lagging behind Mem's, a

Preface: First, thank you for choosingArticleThank you for your support. I hope this series of articles will help you a little. Thank you again. You may want to ask whenCodeThe code will surely come out. I don't want to throw a lot of code as soon as I come up, and then I will explain that the design of the architecture is in the process of thinking. When I think about it, the code will come to the fore. The previous article describes some of

We just created a LINQ to SQL class, and dragged tables in the database into it (you can also add views and stored procedures ). After that, vs2008 automatically generates a series of code, which we will not introduce in detail, but we know that the LTS layer co
