The invention provides a Dores front-end node-based service proxy method and
system, and relates to the technical field of
database access request
processing, and the method comprises the steps: collecting front-end node performance indexes, extracting node performance characteristics through employing multi-head recursive attention and causal
convolution solution, extracting inter-node correlation characteristics through combining graph attention
convolution, and obtaining a
database access request; the method comprises the following steps: constructing a node
state vector, optimizing a multi-layer
connection pool parameter by utilizing an
online learning algorithm, establishing a node
incidence matrix based on comparative learning, constructing a node performance probability graph evolution model through variational reasoning and Monte Carlo sampling, predicting a node performance change trend, and receiving a
database access request; and generating a
query plan by adopting an edge attention
message passing mechanism, carrying out resource evaluation in combination with performance
trend prediction, carrying out scheduling
decision making by utilizing multi-agent
reinforcement learning and Monte Carlo tree search, carrying out fault detection and migration according to node performance deviation, and updating a probability graph evolution model.
