Cloud Object Storage

Cloud Object Storage (COS) is a distributed storage service launched by Tencent Cloud. It has no structure restrictions and is accessible via HTTP/HTTPS protocols. It can store massive amounts of data in buckets featuring unlimited storage space and no partition management requirements, making it especially suitable for a variety of use cases such as data delivery for CDN, data processing for CI, and data lake for big data computation and analysis. Moreover, it provides a web-based console, multilingual SDKs and APIs, as well as command line and graphical tools. It is readily compatible with AWS S3 APIs, allowing direct access to community tools and plugins with ease.

Elastic MapReduce

Combining cloud computing and community open-source technologies such as Hadoop, Hive, Spark, HBase, Presto, and Storm, Tencent Cloud Elastic MapReduce (EMR) provides secure and cost-effective cloud-based Hadoop services featuring high reliability and elastic scalability. Using EMR, you can create a secure and reliable Hadoop cluster in just minutes to analyze petabytes of data stored on the data nodes in the cluster or in Cloud Object Storage (COS).

Persistent Image Processing

OverviewThe following example shows how to automatically process an image when you upload it to COS.When the image is uploaded successfully, COS(Cloud Object Storage) will save both the input and output images. You can later obtain the processing results using a general download request.Persistent Image Processing upon UploadSample code

CDN Cache Purging

OverviewCDN (Content Delivery Network CDN) cache purging is a Tencent Cloud COS (Cloud Object Storage) feature based on SCF (Serverless Cloud Function) to help users automatically purge their data cached on CDN edge servers. If you add a trigger rule to your bucket, then when you update files in the bucket, the SCF function provisioned by COS will be automatically triggered

Working with COSBench

COSBench OverviewCOSBench is an open-source benchmark tool developed by Intel for testing the performance of cloud object storage systems. As a cloud storage system compatible with S3 protocol, COSBench can be used to perform benchmark tests on the read/write performance of Tencent Cloud COS.System EnvironmentIt is recommended that you run COSBench in CentOS 7.0 or a later version. If you run it in Ubuntu,

Limiting Sizes of Uploaded Objects

Cloud Object Storage (COS) supports limiting object sizes upon the upload, which allows you to manage storage space flexibly by avoiding uploading objects that are too large or too small to make full use of the bandwidth and storage space. This document gives two samples to describe how to control the objects sizes in a refined way.PreparationsThe samples use the information below:APPID of the root account: 1250000000Bu

CDN Acceleration Domain Names

Storage Usage Fees

Storage usage refers to the storage used. The rate you are charged depends on the objects size and how long you stored them. For different storage classes, the unit price, minimum object size, and minimum storage duration period are different, which will be described below. The actual costs depend on the use case and storage class of the object. </

Append Object

OverviewThis API is used to upload an object to a bucket in the form of parts. If an object is uploaded using the Append Object API, it will be automatically determined as "appendable", while objects uploaded using other APIs are determined as "normal" (if you upload an object that already exists and the object type is appendable, the object type will be overwritten to "normal").
