// Package workloadbasedlearning implements the Workload-Based Learning Optimizer.
// The Workload-Based Learning Optimizer introduces a new module in TiDB that leverages captured workload history to
// enhance the database query optimizer.
// By learning from historical data, this module helps the optimizer make smarter decisions, such as identify hot and cold tables,
// analyze resource consumption, etc.
// The workload analysis results can be used to directly suggest a better path,
// or to indirectly influence the cost model and stats so that the optimizer can select the best plan more intelligently and adaptively.
package workloadbasedlearning

// Handle The entry point for all workload-based learning related tasks
type Handle struct {

// NewWorkloadBasedLearningHandle Create a new WorkloadBasedLearningHandle
// WorkloadBasedLearningHandle is Singleton pattern
func NewWorkloadBasedLearningHandle() *Handle {
	return &Handle{}
}

// HandleReadTableCost Start a new round of analysis of all historical read queries.
