Variables

var GlobalState = State{

	PrecisionSeconds:      atomic.NewInt64(DefTiDBTopSQLPrecisionSeconds),
	MaxStatementCount:     atomic.NewInt64(DefTiDBTopSQLMaxTimeSeriesCount),
	MaxCollect:            atomic.NewInt64(DefTiDBTopSQLMaxMetaCount),
	ReportIntervalSeconds: atomic.NewInt64(DefTiDBTopSQLReportIntervalSeconds),
	// contains filtered or unexported fields
}

GlobalState is the global Top-SQL state.

Types

type State

type State struct {

	// The refresh interval of top-sql.
	PrecisionSeconds *atomic.Int64
	// The maximum number of statements kept in memory.
	MaxStatementCount *atomic.Int64
	// The maximum capacity of the collect map.
	MaxCollect *atomic.Int64
	// The report data interval of top-sql.
	ReportIntervalSeconds *atomic.Int64
	// contains filtered or unexported fields
}

State is the state for control top sql feature.
