Batch Processing System Architecture Based on AWS cloud services
When AWS executes batch processing tasks, it allows you to configure application architectures for processing multiple jobs as needed, which can be used for instantaneous or delayed deployment of heterogeneous systems, it can also be expanded to a "Grid"
Recently, the project needs to use the AWS S3 API to implement file upload and download function, only to find that the internet about. NET implementation of this feature is not many articles, there are a few are also very old version of the use of AWS description, writing and packaging classes, etc. are basically scrapped. Although this, but still very grateful

1. Rewrite the batch conversion js provided by Baidu to achieve 100 coordinate points at a time
2.Using recursive callbacks to control the return sequence of coordinate transformations to ensure that a set of coordinates (a set of 100) requested first arrives first
First, let's take a look at two examples of coordinate transformation in the demo of Baidu Maps API:

The previous blog said that using the HBase client API to manipulate the records in the HBase table, today we look at how to use the API to bulk manipulate the data in the table.
Install the method in the previous blog if you update (Add/modify/delete) records in HBase, is an update by line, this method in processing a large number of update operations, performance is poor, fortunately in the HBase provides

The bulk processing functionality provided by Elasticsearch is implemented by using the _bulk API. This feature is important because it provides a very efficient mechanism to complete multiple operations as quickly as possible, while using as few network round trips as possible.1, batch index, that is, batch add documentsTwo documents (ID 1-john doe and ID 2-jane
Elasticsearch supports batch addition or deletion of index documents. In Java APIs, bulkrequestbuilder is constructed, batch index/delete requests are added to bulkrequestbuilder, and bulkrequestbuilder is executed. The following is an example:
Import static Org. elasticsearch. common. xcontent. xcontentfactory. *; bulkrequestbuilder bulkrequest = client. preparebulk (); bulkrequest. add (client. prepareind
