Gridfs is a file specification that stores large files in a MongoDB database. first, how to achieve mass storage Because the size of the Bson object in MongoDB is limited, the GRIDFS specification provides a transparent mechanism for dividing a large file into smaller files.

This period of time to see too many people confused with the mass mailing. So I used to write a dongdong to share with you. I hope you can extrapolate. The key is to build a method of its own invocation, and in the case of large amounts of data, use an array instead of a recordset. Its own calls can have a lot of applications. In addition to the bulk of the mail, there are, for example, their own recursion. Many people want to achieve a repeat random

demand, we will be based on the needs of the sub-station to classify the content. For example, the tourism industry, many tourism industries are classified according to the region, even has broken down to the site classification of the sub-station, then the regional classification of the demand has been satisfied very well, then we go to do the timeliness of the classification of the Child station, tourism industry users for the timeliness of the existence of demand, care about a month should

, this is only a negative effect on the user's frequent modification of the record, especially the index, but has no effect on the query speed. In the office automation system, whether the system home page to show the need for the user to sign the file, the meeting or the user file query, and so on in any case data query can not be separated from the field is "date" and the user's own "user name."

the future data development to one hours 100w, press now 100ms, a thread processing 10 times a minute 60 * 10 times, one hours 60*10 * 60 times = 36,000 times, one day 60*10*60*24 = 86 4,000 times. Our target is 100w times a day, which can be done by adding two threads. But what if it takes one hours and 100w? Then you need to add 30 threads and corresponding hardware resources to ensure that the speed can be achieved, so the cost is up. Can there be a better way to improve the efficiency of ou

Bloom filter uses an array of M-bits to hold the information, the Bloom filter is an array of bits with M-bits in its initial state, with each bit set to 0, that is, the elements of the entire array of the BF are 0. 2) K Independent hash function To express s={x1, X2,..., xn} A collection of n elements, Bloom filter uses K-independent hash functions (hash function), which map each element in the collection to the scope of {1,..., m}, respectively. When we add any element x to the bloom filter,

the effect of error correction. Therefore, the optimization algorithm for the first character filtering has some limitations.Step-by-step optimization We think about this problem, because the pattern string q is a set, there must be a lot of pattern strings with a common prefix. Can you use this prefix for optimization?Optimization 1: Optimized with the same prefix for two words For example: strings explore and explain, they have a public prefix, whi
