Problems solved by technology

[0003] However, the inventor found in the process of implementing the present invention that the above-mentioned method in the prior art has at least the following defects: Since the consumption task consumes from the oldest data offset position every time it is started, if the consumption task If the task is interrupted and restarted multiple times during the consumption process, it will consume from the offset position of the oldest data in the message queue after each restart, which may cause repeated consumption of data, which reduces consumption efficiency , and easily lead to consumption errors

Embodiment 1

[0028] figure 1 It shows a schematic flowchart of a message queue consumption method provided by Embodiment 1 of the present invention, and the method includes:

[0029] Step S110: When the consumption task starts, establish a communication connection with the background database.

[0030] Wherein, the consumption task refers to the task of reading and processing the message queue at the consumer end. Among them, one message queue may correspond to one or more consumption tasks, and one consumption task may also correspond to one or more message queues. When a consumption task is started, the consumption end executing the consumption task establishes a communication connection with the background database. The communication connection can be established in various ways, which is not limited in the present invention. Wherein, the start of the consumption task includes various situations such as starting the consumption task for the first time and restarting the consumption ta...

Abstract

The invention discloses a message queue consumption method and device, and at least can solve the technical problem of double spending caused by consumption from the oldest data offset position of a message queue after restart of every time in the prior art. The method includes the steps: building communication connection between a consuming task and a background database when the consuming task is started; acquiring current offset information of the message queue corresponding to the consuming task from the background database through the communication connection; reading message data in the message queue according to the acquired current offset information if the current offset information is successfully acquired; updating the current offset information of the message queue in the background database according to an offset address corresponding to the message data after the message data are read from the message queue.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a message queue consumption method and device. Background technique [0002] At present, after a business front-end producer generates a message, it usually stores the message to be processed in the message partition of the message queue, and then sends it to the back-end consumer for processing. In the prior art, whenever a consumption task at the consumer end is started, consumption starts from the oldest data offset position (that is, the data position with the earliest storage time) by default. [0003] However, the inventor found in the process of implementing the present invention that the above-mentioned method in the prior art has at least the following defects: Since the consumption task consumes from the oldest data offset position every time it is started, if the consumption task If the task is interrupted and restarted multiple times during the consumption pro...
