Expand description

Policy defining how to combine multiple responses into one.

Variants§

§

OneSucceeded

Wait for one request to succeed and return its results. Return error if all requests fail.

§

OneSucceededNonEmpty

Wait for one request to succeed with a non-empty value. Return error if all requests fail or return Nil.

§

AllSucceeded

Waits for all requests to succeed, and the returns one of the successes. Returns the error on the first received error.

§

AggregateLogical(LogicalAggregateOp)

Aggregate success results according to a logical bitwise operator. Return error on any failed request or on a response that doesn’t conform to 0 or 1.

§

Aggregate(AggregateOp)

Aggregate success results according to a numeric operator. Return error on any failed request or on a response that isn’t an integer.

§

CombineArrays

Aggregate array responses into a single array. Return error on any failed request or on a response that isn’t an array.

§

Special

Handling is not defined by the Redis standard. Will receive a special case
