Netflix gutted Tudum’s old read path—Kafka, Cassandra, layers of cache—and swapped in RAW Hollow, a compressed, distributed, in-memory object store baked right into each microservice.
Result? Homepage renders dropped from 1.4s to 0.4s. Editors get near-instant previews. No more read caches. No external datastore reads. Just raw speed.
The bigger picture: Data lives in memory, right next to the code that needs it. No asking the network. No waiting. It's memory-local architecture instead of the usual DB-plus-cache juggling act.
