Transaction pool dynamic telescoping method, device, and storage medium

Abstract

The invention provides a transaction pool dynamic scaling method, a device and a storage medium. The method comprises the steps: monitoring a real-time memory usage value of a current device, and updating an average memory usage value in a first period according to the real-time memory usage value; monitoring whether the residual capacity of the transaction pool of the current node is not greaterthan a first threshold; if so, determining an average memory idle value of the current period according to the total memory of the current equipment and the average memory use value of the current period; determining the extensible capacity of the transaction pool according to the average memory idle value, the average transaction size and the safety coefficient; and expanding the transaction poolcapacity of the current node according to the extensible capacity of the transaction pool. According to the method, the memory performance of the equipment is fully utilized, and the capacity of thetransaction pool is dynamically expanded.

Description

technical field [0001] The present application relates to the technical field of the Internet, in particular to a method, device and storage medium for dynamic expansion and contraction of a transaction pool. Background technique [0002] In the existing blockchain system, after the node receives the transaction, it caches the transaction in the transaction pool when the local transaction pool is not full, and discards the transaction when the local transaction pool is full, or replaces the order in the transaction pool end of the deal. When the blockchain system is under high load, many blockchain services will be blocked. [0003] In order to ensure that all devices can run the blockchain program normally, in the existing blockchain system, the capacity of the transaction pool is configured as a fixed value suitable for common devices, for example, 1024 transactions, or 4096 transactions, etc. For many devices with good or excellent memory configuration, the capacity of ...

AI Technical Summary

Problems solved by technology

For many devices with good or excellent memory configuration, the capacity of the default configuration often cannot fully utilize the performance of the device

Although some existing blockchain systems support externally resetting the transaction pool capacity through instructions, the artificially reset capacity usually cannot match the actual usage of the device well.
