Is the new Redis-like store called Plasma?

  • None: Just asking a question out of curiosity

After reading

I know Ray stopped not using Redis, and created a Redis-like store.

I saw a term Plasma in the white paper’s Appendix - Architecture diagram:

Question 1

Just confirm this the new Redis-like store refers to Plasma, right?

Question 2

Also, in the white paper, I only saw Object Store is being referred as Plasma.
What about Global Control Store (GCS), is GCS also using Plasma? Thanks! :smiley:

Redis is the backend of Global Control Store; so it’s not plasma/object store.

You can think plasma/object store is for storing user data in the data plane, whereas the gcs store/redis is for storing ray cluster metadata in the control plane.
