Can we go with a database but without a cache layer in 2024?
summary
Benchmarks compare running high-load services with only a database versus using cache layers, using hardware with a 48-core Xeon and databases PostgreSQL and MySQL plus many Memcached and Redis instances. The presenter used tools redis-benchmark, xwrk and k6 to measure performance and discusses results and concerns encountered during testing (notably an issue with k6).
