Info

MyBatis @Mapper interface for the Agent global usage statistics table with atomic delta upserts.

Methods

Method	Return	Description
selectAll()	List<AgentUsageStats>	List all model usage statistics

upsertDelta(modelName, deltaInputTokens, deltaCachedTokens, deltaOutputTokens, deltaReasoningTokens, deltaRequestCount, deltaCostMicroFen, updatedAt)	int	Atomic increment via INSERT ... ON DUPLICATE KEY UPDATE

Upsert Behavior

The upsertDelta method uses MySQL's INSERT ... ON DUPLICATE KEY UPDATE pattern. All delta values are added atomically to the existing cumulative totals, ensuring concurrent requests are safely merged without race conditions.
