Abstract
The invention discloses a method for supporting million user data sub-meter based on a Hash algorithm. The method comprises the following steps: step S01, allocating an ID value for a user name, and returning a corresponding character string through a Hash function to obtain a Key value; step S02, establishing a target table name by user data through the Key value; step S03, generating a user table named by the target table name in a database storage table; and step S04, inputting the user name, calculating table name of the data storage table through the Hash function, and accessing a corresponding table. The method, compared to the prior art, is simple in design, high in data table operation efficiency and high in availability.
Description
Technical field
The present invention relates to Computer Database submeter technology, be specifically related to a kind ofly based on hash algorithm support ten million user data, divide table method.
Background technology
Website user is increasing.Relevant data-storing to user, and the optimization that user data reads is most important.This is related to the height of website to user experience, and website most important be exactly to serve user.If user feels registration login and waits the slow experience of associative operation bad, can have a strong impact on the use of website.When user data reaches millions of, in the time of up to ten million, the mono-table inquiry of the mysql time once can double.If there is complex query, may be stuck at that.
The expansion of Mysql cluster is high, need not change sql statement, easily implement, but the data volume of single table is large, and length consuming time carried out in wall scroll statement, and server cost is too high.
Summary of the invention
The present invention has overcome the deficiencies in the prior art, provides a kind of and divides table method based on hash algorithm support ten million user data.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
Based on hash algorithm support ten million user data, divide a table method, comprise the following steps:
Step S01, distributes an ID value to user name, by Hash function, returns to respective symbols string, obtains a Key value;
Step S02, user data, by described Key value, creates object table title;
Step S03, generates the subscriber's meter with described object table name nominating in database storage list;
Step S04, inputs user name, calculates the table name of table data store by Hash function, then the corresponding table of access.
The character string of returning by Hash function is scale-of-two or sexadecimal.
More preferably, character string is 4 character strings.
Compared with prior art, beneficial effect of the present invention has: the built-in user's algorithm of multiple servers, is stored into user name in different tables by user according to certain unique algorithm, improve the performance of single table, some conventional fields are gathered user-friendly, improve operating efficiency, increase availability.
Accompanying drawing explanation
Fig. 1 is method flow diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
Based on hash algorithm support ten million user data, divide a table method, comprise the following steps:
Step S01, distributes an ID value to user name, by Hash function, returns to respective symbols string, obtains a Key value;
Step S02, user data, by described Key value, creates object table title;
Step S03, generates the subscriber's meter with described object table name nominating in database storage list;
Step S04, inputs user name, calculates the table name of table data store by Hash function, then the corresponding table of access.
The character string of returning by Hash function is scale-of-two or sexadecimal.
More preferably, character string is 4 character strings.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
