Embodiment 1
[0045] Embodiment 1: The present invention proposes a method for implementing short-term data writing library, comprising the following steps:
[0046] Step 1: The process of set assembly according to the business demand plan calculation model is as follows:
[0047] S11, a virtual slot is established based on a foreign key field value of a business unit corresponding to a KEY, and the FNV (FowlerNolVo) algorithm is used to hash the field value. The FNV-1 algorithm can hash a large amount of data while maintaining a small conflict rate. The calculation process is,
[0048] initialization: hash=2166136261;
[0049] Enter the loop and determine the number of loops according to the length of the input data bytes. The hash result is a 32-bit unsigned integer, so it is necessary to discard the high bits and keep the low 32 bits: hash=(2166136261*16777619) mod 2 32 = 0x050c5d1f;
[0050] To perform XOR operation, first convert 0x56 to 32-bit value 0x00000056, and then perform XOR...
Embodiment 2
[0079] Embodiment 2: The present invention also proposes an implementation system for short-term data writing library, including:
[0080] The set assembly module is used to execute: according to the business demand plan, the billing model is assembled and assembled, and the billing result set is generated;
[0081] A parsing module for executing: parsing the billing result set and putting it into a memory queue;
[0082] A queue pulling module for executing: spin-pulling queue data from the memory queue;
[0083] A token access module for executing: creating an access token to connect to the database according to the queue data;
[0084] The archiving module is used to perform: batch archiving of multi-data sources of calculation collection;
[0085] The task judgment module is used to execute: judgment task return token;
[0086] The exception collection module is used to execute: establish a collection container for abnormal tasks of volume fee.
Embodiment 3
[0087] Embodiment 3: The present invention also proposes an electronic device, including a memory, a processor, and a computer program stored in the memory and running on the processor, characterized in that the processor implements the method when executing the program. step.

Abstract
The invention discloses a method, a system and an electronic device for implementing short-term data writing library. The method includes the following steps: Step SS1: assembling and assembling a billing model according to a business demand plan, and generating a billing result set; Step SS2: parsing the The billing result set is put into the memory queue; Step SS3: Spin and pull queue data from the memory queue; Step SS4: Create an access token to connect to the database according to the queue data; Step SS5: Set multiple data for billing The source batch is archived; Step SS6: Judging the task return token; Step SS7: Establishing a collection container for abnormal amount and charge tasks. The present invention adopts an asynchronous and non-blocking working mode based on the flow control write-back mechanism, which avoids the problem of synchronous blocking between write-back sets, and the flexible batch write-back mechanism effectively improves the data processing and data writing of volume cost calculation. library performance.
