Implements #18008
TODO: add design info
Description
Creates a RecordSupplierGroup which can mux calls across multiple
RecordSupplier
instances. Currently keeping it so every indexing task is only reading from a single consumer (not multiple) as it is simplest (and no noisy neighbor), but this is liable to change especially with scaling. The only place where thispoll()
is called against multiple consumers in parallel is during data sampling in the data loader UI.Release note
