Functions

func HasFieldKeyOrValue 

func HasFieldKeyOrValue(expr influxql.Expr) (bool, bool)

func HasSingleMeasurementNoOR 

func HasSingleMeasurementNoOR(expr influxql.Expr) (string, bool)

HasSingleMeasurementNoOR determines if an index optimisation is available.

Typically the read service will use the query engine to retrieve all field keys for all measurements that match the expression, which can be very inefficient if it can be proved that only one measurement matches the expression.

This condition is determined when the following is true:

  • there is only one occurrence of the tag key `_measurement`.
  • there are no OR operators in the expression tree.
  • the operator for the `_measurement` binary expression is ==.

func NodeToExpr 

func NodeToExpr(node *Node, remap map[string]string) (influxql.Expr, error)

NodeToExpr transforms a predicate node to an influxql.Expr.

func PredicateToExprString 

func PredicateToExprString(p *Predicate) string

func RegisterStorageServer

func WalkNode 

func WalkNode(v NodeVisitor, node *Node)
