As one of the core services of cloud computing, storage services are used by every user. However, the current situation is: most customers in addition to virtual machine data disk (persistent disk), and does not fully utilize the storage services. Let's look at a typical scenario: for example, a Web application needs a user to upload an invoice scan (image file).

wonder why the need for data segmentation? A mature and stable database such as Oracle, sufficient to support the storage and query of massive data? Why do I need data slicing? Indeed, Oracle's db is really mature and stable, but high usage costs and high-end hardware support are not affordable for every company. Imag

Recently, data storage industry analysts, manufacturers and financiers gathered in the BD conference in Boston to present their views on the storage and IT industry for the coming year.It sales growth is much smaller than it was 10 years ago, and users are trying to tap into their existing IT environment for every single point of efficiency potential. Virtualizat

saves up to 50% of the occupied space. In addition to high performance, eternus dx200f can better meet the big data processing needs. For example, eternus dx200f can copy data and supports automatic configuration streamlining. Eternus dx200f adheres to the high-reliability technology widely acclaimed in the eternus DX series, and implements redundancy for controllers, power supplies, and other main compon

word length) is an important feature in the structure of a computer system. Word length is determined by the type of CPU, different computer systems, the word length is different, the common 8-bit, 16-bit, 32-bit, 64-bit, the longer the word length, the more information the computer processing, the higher the accuracy, the word length is an important indicator of computer performance, At present, the mainstream microcomputer is changing from 32-bit machine to 64-bit machine.Note the difference

vitess Each MySQL connection has a memory cost that ranges from 256KB to almost 3MB, depending on the MySQL version you are using. As your user base grows, you need to increase the memory to support the increased connections, but increasing the memory does not help to improve the query speed. In addition, there is a lot of CPU overhead when getting these connections. Vitess BSON-based protocols create very lightweight c

data must be in the same domain name as the script executing the call, or the request will fail. HTML storage is similar, and it is the simplest combination of Ajax. The important factor in this way of data format is speed, where HTML code snippets can be exported directly to the DOM without parsing the client, so we don't need to write JavaScript code to parse

produce fragmented data, and add three hundred or four hundred megabytes of a single file, just 11 seconds more to complete the operation, And even files with such a large file copy can take at least twenty or thirty seconds to complete, visible MongoDB has very high performance in bulk file storage. The detailed fragmentation can be viewed by entering the Db.printshardingstatus () command on the client's

deduplication? This starts with the data stored on the primary storage. Unlike a backup, in primary storage, the system is at any time in the I/O exchange operation, the primary storage data changes are occurring at any time, this feature also determines that primary

disadvantage of row storage is also obvious, for example, it cannot support fast query processing because it cannot skip unnecessary column reads when the query is only for a few columns in a multiple list, and because of the combination of columns with different data values, row storage is not easy to obtain a very high compression ratio, that is, space utiliza

same for a file system or a file system for a period of time. In addition to the first part, these three problems are economically considered, to address other problems, the file system does not provide any stable protocols to support business data management except file management. It is precisely because of the non-dependence of the file system on human conventions that we have a need for other solutions. Let's take a look at what

Recently there is a need to store large amounts of small data, about billions of of the scale, each data is 6 bits of the number plus a 32-bit MD5 (16 binary display). Because the data is very small, the amount of data is not large, we plan to do shards according to MD5, stored in multiple redis, each redis about 100 m

The Indexed organization table for mysq,oracle is the data stored in the primary key order (in-page).If the data insertion order is inconsistent with the primary key, there is no guarantee that the pages will be stored in a physical order. The cost of moving data blocks is significant. The
