Mongodb Use Database In Script

From an article in the Openmymind blog, the author introduces two MongoDB monitoring gadgets, Mongospy and Mongowatch, which they write with Node.js, and then puts forward the idea of using compression to save space when storing text in MongoDB. These two gadgets are not very powerful and simple to implement, and if you can manipulate MongoDB in any language, believe you can write a similar thing. Mongospy: A MongoDB slow query to monitor ...

To make it easier for everyone to introduce analytics into their large data storage systems, Pentaho today announced that the latest version of its Business analytics and data integration platform has officially entered the general phase. The Pentaho 5.1 is designed to provide a bridge between the "data and analysis two separate realms" to support all Pentaho users-from developers to data scientists to business analysts. Pentaho 5.1 for the direct MONGODB data storage system brought to run without making ...

In mailbox rapid expansion process, one of the performance problems is the MongoDB database level write lock, the time spent in the lock waiting process, directly reflects the user's use of the service process delay. To address this long-standing problem, we decided to migrate a common set of MongoDB (storing mail-related data) to a separate cluster. According to our inference, this will reduce the lock latency by 50%, and we can add more fragments, and we expect to be able to optimize and manage different types of data independently. We start from Mon ...

"Editor's note" This blog author Luke Lovett is the MongoDB company's Java engineer, he demonstrated MONGO connector after 2 years of development after the metamorphosis-complete connector at both ends of the synchronization update. , Luke also shows how to implement fuzzy matching by Elasticsearch. The following is a translation: the introduction assumes that you are running MongoDB. Great, now that you have an exact match for all the queries that are based on the database. Now, imagine that you're building a text search work in your application ...

The chief technical officer of Schindler Yuncheng (Speedycloud) Dong at the meeting with a speech entitled "Automation extension of NoSQL cluster on the Yunping platform". Demonstrates how to create and initialize a NoSQL cluster on a cloud host, and how to detect a host failure through a monitoring system, and automatically invoke the cloud API for faulty device replacement, and finally show how to destroy a host from the command line. But because the time is hasty, did not give the small partner to leave too many time to carry on the question solution and the difficulty detailed introduction, therefore dong in ...

After Facebook abandoned Cassandra, HBase 0.89 was given a lot of stability optimizations to make it truly an industrial-grade, structured data storage retrieval system. Facebook's Puma, Titan, ODS time Series monitoring system uses hbase as a back-end data storage System. 　　HBase is also used in some projects of domestic companies. HBase subordinate to the Hadoop ecosystem, from the beginning of the design of the system is very focused on the expansion of the dynamic expansion of the cluster, load are ...

In the past, assembly code written by developers was lightweight and fast. If you are lucky, they can hire someone to help you finish typing the code if you have a good budget. If you're in a bad mood, you can only do complex input work on your own. Now, developers work with team members on different continents, who use languages ​​in different character sets, and worse, some team members may use different versions of the compiler. Some code is new, some libraries are created from many years ago, the source code has been ...

The Docker has been in use for more than a year and has been installed on both local Linux systems and cloud platforms. At that time learned a lot about managing mirroring, the flexibility to create mirrors for any platform, learn to write some of your own programs that are not relevant to Docker. I've tried to summarize my experience to the following five points, providing references for those who just started using Docker. When making a mirror you need to be particularly clear I try to run my application without the root user. Most Linux distributions have one advantage: when you install a service, the operating system ...

Using Redis to develop applications is a pleasant process, but as with other technologies, you need to remember a few things as well, based on Redis application design. Before, you might have a chest of the whole pattern of relational database development, and REDIS application development has many similarities, but you have to keep in mind that the following two points--redis is a memory database, and it is single-threaded. Therefore, when using Redis, you need to pay attention to the following points: 1. Master all key databases stored in Redis ...

The "Editor's note" Container technology is a lightweight virtualization technology that allows you to virtualize a stand-alone system's operating environment with fine-grained granularity. This means that a physical server, or a virtual server above a cloud, can run hundreds of separate containers at the same time. Based on the distinctive features of "fast" in the gaming industry, every business logic, such as the control of character walking, fighting, scene, chatting, archiving, database, etc., can be run in a separate container. This series of containers constitutes the autonomous system of an independent gaming world. ...
