There are two main components of Kong: Kong Server: Nginx-based server used to receive API requests.Apache Cassandra: U

,twitter and digg.com are using Cassandra. The main characteristic of Cassandra is that it is not a database, but a distributed network service composed of a bunch of database nodes, a write operation to Cassandra will be copied to the other nodes, and the read operation to Cassandra will be routed to a node to read.

Tags: small and medium-sized enterprises big data technology route Selection of big data technology routes for Small and Medium-sized Enterprises Currently, big data is mainly used in the Internet and e-commerce fields, and is gradually used in the telecom and power industries. For the majority of small and medium-sized enterprises, big data has heard too much. However, the technical threshold for big data is still high. From the technical line, choosing the technical solutions used by large com

Recently, Twitter developed a distributed real-time statistics system, Rainbird. Usage Rainbird can be used for real-time data statistics: 1. count the number of clicks on each page and domain name on the website 2. Internal System Operation Monitoring (count the running status of the monitored server) 3. Record the maximum and minimum values Performance Requirements As a distributed application of large websites, the following performance is required: 1 High Write Performance, up to 100,000 WP

following way: All events generated by the original system should be marked with a timestamp. When the processor in the pipeline processes the stream, it tracks the maximum timestamp, assuming that the persisted global clock is behind, and updates it to the maximum timestamp. Time synchronization of other processors with the global clock While the data is being played back. Resets the global clock. Persisted storage RollupWe've discussed how persistent storage can be used

. You might as well build a relational db cluster, but they're using shared storage, which is not the type we want. So there's a nosql era in which Google, Facebook, and Amazon are trying to handle more transmissions.NoSQL eraThere are a lot of NoSQL databases now, such as MongoDB, Redis, Riak, HBase, Cassandra, and so on. Each one has one of the following features: No longer use the SQL language, such as MongoDB,

require huge overhead and a performance cap, and it's never possible to use a single machine to support all of the load on Google and Facebook. In view of this situation, we need a new database because the relational database does not run well on the cluster.

Databases are generally divided into the following types: relational (transactional) databases, represented by Oracle and MySQL, with keyValue databases, represented by redis and memcached dB, there are document-based databases such as MongoDB, and columnar databases represented by hbase, Cassandra, and Dynamo, as well as other graphic databases, object data libraries, and XML databases. Some databases are distributed database design concepts, such as

on the feasibility of Big Data 3.0 replacing SAP HANA First, Big Data 3.0 Introduction In short, Big Data 3.0 is about implementing SQL on the big data and balancing performance, ease of use, and scalability. At present, "search engine + Large data +sql" such a convergence as one of the trend. Let's take a look at some of my other posts: 1.

: Traditional enterprise database vendors often propose that NoSQL lacks professional monitoring and management tools. Their argument is that enterprise applications need to fine-tune and monitor databases to ensure stable performance and operation. The NoSQL vendor's point of view is that the lack of such degree does not help RDBMS in solutions. Many NoSQL vendors also try to differentiate their monitoring and management software levels, such as Cassandra
