The short version

  • Only Memcached has a free tier, so it costs nothing to try first.
  • Each has a real cost: Fivetran HVR pricing not published separately; part of Fivetran's usage model; Memcached no persistence at all: restart a node and its cache is gone, which every design must assume
  • They diverge on capability: Fivetran HVR covers Log-based change capture, Memcached covers In-memory key-value cache.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Fivetran HVR

  • Pricing not published separately; part of Fivetran's usage model
  • Requires Fivetran relationship for implementation
  • Limited standalone documentation and community resources
  • May be overkill for simple batch replication needs
  • Competitive offerings provide more transparent per-connector pricing

Memcached

  • No persistence at all: restart a node and its cache is gone, which every design must assume
  • No replication or failover, so losing a node loses that share of the cache
  • Only simple key-value, with none of the lists, sorted sets or streams Redis offers
  • Values are capped at 1MB by default, which surprises teams caching large documents

Memcached is a pure cache: simpler, multithreaded and very predictable. Redis adds persistence, replication and rich data structures, which is why it is the default choice unless you specifically want a cache and nothing more.

Memcached: Does Memcached persist data?

No. Everything is in memory and lost on restart, by design.
