Introduction
Google cloud dataflow is a method for building, managing, and optimizing complex data processing pipelines. It integrates many internal technologies, for example, flume for Efficient Data Parallel Processing and millwheel with a good Fault Tolerance Mechanism for stream processing. Dataflow's current API is only available in Java (in fact, flume itself provides multiple Java/C ++/Python interfa
In 2004, Google published a very influential paper introducing the mapreduce framework to the world, which can break down an application into many parallel computing commands, massive datasets run across a large number of computing nodes. Today, mapreduce has become a highly popular infrastructure and programming model in the field of parallel distributed computing. It is the foundation of Apache hadoop, it is used by many well-known manufacturers to
The top 10 most frequently used words in the statistics file (C # TPL DataFlow ),
Recently, the company held a program writing competition, requesting that the top 10 words frequently appear in 2G files.
The original idea was to use the dictionary tree. Later, it was found that the dictionary tree is more suitable for searching for prefixes and is highly efficient in searching for non-hash tables.
Then, the Hash table and

Today, I wrote a small program and used TPL Dataflow. As a result, I found a problem during deployment: the customer's server contains win2003 machines, and 2003 is not supported. net 4.5, but TPL Dataflow can only be in.. net 4.5 program.
I searched on the Internet and someone discussed this issue on the MSDN Forum. The conclusion is that although MS is intended to support it. net 4.0, but there is no cor

In the Google RESTFul API, the Google Blogger API (Google Blog API) should be close to our lives, as nearly a lot of people are reading blogs every day and have heard of blogs. In a series of articles in front of Google's application system for integration (5) and Google's Applications for integration (6). We mentioned how to convert the JSON schema of

There are some Google API introductions, but in actual development we may need to convert the JSON data returned by the Google RESTful API into XML data input into a third-party system, which is very common in enterprise application integration. Then there is the question of how to ensure that the converted XML data format is canonical, which requires XML Schema (XML) for validation. Now the point is, we on
