ReadLabel

Purpose

The ReadLabel specifies which keys a transaction may and will read from. The rationale behind this information is that if a transaction definitely reads from a set of keys, the corresponding KVSReadRequests can be issued even before spawning an executor.

Structure

Field Type Description
will_read KVSKey set in V1, this is a generic set of keys that will be read
may_read KVSKey set in V1, this is a generic set of keys that may be read

From V2 onward, after imposing a tree-structure on keys (or something similar), we can represent potentially infinite sets of keys.

Notes

Occasionally, we refer to "may read"-keys also as lazy reads as they potentially only issued on demand.
