type LastSelector 

type LastSelector struct {

The reason for this is that it was easier to ensure a correct implementation of 'last' by defining it as a row selector when using multiple column readers to iterate over a Flux table.

type MergeJoinCache 

type MergeJoinCache struct {
	// contains filtered or unexported fields

MergeJoinCache implements execute.DataCache This is where the all the tables to be joined are stored.

buffers: Buffers to hold the tables for each incoming stream.

postJoinKeys: The post-join group keys for all joined tables. 

These group keys are constructed and stored as soon
as a table is consumed by the join operator, but prior
to actually joining the data.

reverseLookup: Each output group key that is stored is mapped to its 

corresponding pre-join group keys. These pre-join group
keys are then used to retrieve their corresponding
tables from the buffers.

tables: All output tables are materialized and stored in this 

map before being sent to downstream operators.

ForEach iterates over each table in the output stream

func (*MergeJoinCache) ForEachWithContext
