< method examples >
FIG. 3 is a schematic flow chart diagram of a method for allocating information flows of one embodiment.
In one or more embodiments of the present description, the method illustrated in FIG. 3 may be implemented by a server system, which may be the server system 1100 illustrated in FIG. 1.
As shown in fig. 3, the method of the present embodiment includes the following steps S302 to S308:
step S302, obtaining the target information flow to be distributed.
In one or more embodiments of the present description, an information stream is passed through server system 1100-1 to server system 1100-2 and then to server system 1100-3, each of which performs different processing on the information stream and forwards the request downstream.
The target information flow is required to execute the information flow distributed by the server system of the embodiment of the present specification. The target information stream may be generated by the terminal device 1200 and directly transmitted to the server system executing the embodiment of the present specification, or may be obtained by processing the information stream generated by the terminal device 1200 by another server system and transmitted to the server system executing the embodiment of the present specification.
Step S304, determining the dependency relationship between the target information flow and the plurality of server systems.
Wherein the dependency indicates that the target information stream depends on the historical information streams stored in the corresponding server system.
Specifically, the server system stores the history information stream, and may include that the history information stream is stored in the server system, or the server system processes the history information stream.
In one or more embodiments of the present description, determining the dependency relationship between the target information stream and the plurality of server systems may include steps S3042 to S3044 shown as follows:
step S3042, an identifier of the target information stream is acquired as the target identifier.
In one or more embodiments of the present description, the identification of the information stream may be made up of numbers and/or characters. The identification of the target information stream may correspond to the identification of the dependent history information stream, i.e. the identification of the target information stream may be the same as, or have a correspondence with, the identification of the dependent history information stream.
For example, the target identification of the target information stream may be AAFEF-2, and the identification corresponding to the target identification may be AAFEF-? Wherein? And may represent any number and/or character.
In one embodiment of the present description, the identification of the information flow may be an order number. For example, the target information stream may be a refund information stream and the identified historical information stream corresponding to the target identification may be a purchase information stream.
Step S3044, determining a server system where the history information stream having the identifier corresponding to the target identifier is located, so as to obtain the dependency relationship.
In this embodiment, the target information stream may depend on the server system where the identified historical information stream corresponding to the target identifier is located. For example, if a historical information stream of identities corresponding to the target identity is stored in the server system 1100-2, then the target information stream may be determined to be dependent on the server system 1100-2.
In one or more embodiments of the present description, determining a server system where a historical information stream having an identity corresponding to the target identity is located to obtain the dependency relationship may further include:
step S30442, a preset power table is obtained, where a correspondence between the identifier of the history information stream and the server system is recorded in the power table.
In one or more embodiments of the present description, the identification of all historical information streams (including the historical information streams stored in all server systems) and the server system in which each historical information stream is located are recorded in an idempotent table. From the idempotent table, the server system in which each historical information stream is located can be determined.
The idempotent table may be updated as the information flow increases.
Step S30444, query the idempotent table according to the target identifier to obtain the dependency relationship.
In one or more embodiments of the present specification, it may be determined whether an identifier corresponding to the target identifier is included in the identifiers of the history information streams recorded in the power-equivalent table; determining that the target information stream depends on a corresponding server system in the case of containing the identifier corresponding to the target identifier, wherein the corresponding server system may be a server system where a history information stream of the identifier corresponding to the target identifier is located; in case no identity corresponding to the target identity is included, it is then determined that the target information stream is not dependent on the plurality of server systems, i.e. the target information stream is not dependent on any server system.
And step S306, determining a server system corresponding to the target information stream as a target server system according to the dependency relationship.
In one or more embodiments of the present specification, determining a server system corresponding to a target information flow according to a dependency relationship may include, as the target server system: in the case where the target information stream is determined to be dependent on the corresponding server system, the corresponding server system is taken as the target server system.
In one or more embodiments of the present specification, determining a server system corresponding to a target information flow according to a dependency relationship may include, as the target server system: and under the condition that the target information flow is not dependent on the plurality of server systems, determining the target server system according to a preset matching rule.
In one or more embodiments of the present specification, determining the target server system according to the preset matching rule may include:
carrying out Hash operation on the target identifier to obtain a Hash value of the target identifier;
performing modular operation on the hash value based on the set value to obtain a module of the target identifier;
and determining the target server system according to the model of the target identifier.
The hash operation is to transform an input of arbitrary length into an output of fixed length by a hash algorithm. After the hash operation is performed on the target identifier, the obtained hash value of the target identifier may be an integer number. Since different inputs may hash to the same output, hashing different target identifications may result in the same hash value.
The setting value may be a specific value preset according to an application scenario or specific requirements, for example, the setting value may be, but is not limited to, 100. The norm of the target value is smaller than the set value.
And performing modular operation on the hash value based on the set value, specifically calculating an integer quotient obtained by dividing the hash value by the set value, calculating a product of the integer quotient and the set value, and calculating a difference value between the hash value and the product, namely the module of the target identifier.
For example, if the hash value is a and the setting value is b, then performing a modulo operation on the hash value based on the setting value can be expressed as: and c is a/b, and r is a-c b, wherein r is the modulus of the target mark.
In one or more embodiments of the present description, the manner of determining the target server system according to the model of the target identifier may include:
the value range corresponding to each server system is predetermined, and the value ranges can cover all non-negative integers smaller than the set value. The target server system corresponding to the target information stream can be determined by determining which server system the modulus of the target identifier belongs to.
For example, the numerical range corresponding to the server system 1100-1 includes [0, 50 ], the numerical range corresponding to the server system 1100-2 includes [50, 99], and then, in case that the modulus of the target identifier is greater than or equal to 0 and less than 50, the target server system corresponding to the target information stream may be determined as the server system 1100-1; in the case that the modulo of the target identifier is greater than or equal to 50 and less than or equal to 99, the target server system corresponding to the target information stream may be determined to be the server system 1100-2.
In one or more embodiments of the present description, the manner of determining the target server system according to the model of the target identifier may include:
the mantissa corresponding to each server system is predetermined, and the target server system corresponding to the target information stream can be determined by determining which server system the mantissa of the modulus of the target identifier corresponds to. Where the mantissa of the modulus of the target identification may be the last bit of the value. For example, if the modulo of the target identifier is 14, then the mantissa of the modulo of the target identifier is 4; for another example, if the modulo of the target identifier is 1, then the mantissa of the modulo of the target identifier is 1.
For example, if the mantissa corresponding to the server system 1100-1 includes 1, 3, 5, 7, and 9, and the mantissa corresponding to the server system 1100-2 includes 2, 4, 6, 8, and 0, then if the mantissa of the modulo of the target identifier is any one of 1, 3, 5, 7, and 9, it may be determined that the target server system corresponding to the target information stream is the server system 1100-1; if the mantissa of the modulus of the target identifier is any one of 2, 4, 6, 8, and 0, it may be determined that the target server system corresponding to the target information stream is the server system 1100-2.
In one or more embodiments of the present specification, the determining the target server system according to the preset matching rule may include:
and determining a target server system corresponding to the target information flow according to the acquisition time of the target information flow.
Specifically, a time period corresponding to each server system may be predetermined, and the target server system corresponding to the target information stream may be determined by determining to which server system the acquisition time of the target information stream belongs.
For example, the time period corresponding to the server system 1100-1 is 00:00 to 18:00, and the time period corresponding to the server system 1100-2 is 18:01 to 24:00, then if the acquisition time of the target information stream is between 00:00 to 18:00, the target server system corresponding to the target information stream may be determined to be the server system 1100-1; if the time of acquiring the target information stream is between 18:01 and 24:00, the target server system corresponding to the target information stream may be determined to be the server system 1100-2.
In one or more embodiments of the present specification, the determined target information flow independent of the plurality of server systems may be a plurality, and then determining the target server system according to a preset matching rule may include:
and determining a target server system of the target information flow according to a preset distribution proportion corresponding to each server system.
