Functions ¶

func GetPartitionedBufferIdx ¶ added in v0.9.0

func GetPartitionedBufferIdx(vertexInstance *dfv1.VertexInstance) func(toVertex string, toVertexPartitionCount int32) int32

GetPartitionedBufferIdx returns a function that returns a partitioned buffer index based on the toVertex name and the partition count it distributes the messages evenly to the partitions of the toVertex based on the message count(round-robin)
