Is Memcached or Vitess better?

Neither clearly leads. Memcached starts at Free and Vitess at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.

Which is cheaper, Memcached or Vitess?

Memcached starts at Free and Vitess at Free.

Does Memcached or Vitess run on more platforms?

Memcached runs on Linux, macOS, Windows, Docker, Self-hosted. Vitess runs on Linux, macOS, Docker, Kubernetes.

Can I use Memcached for free?

Both have a free tier, so you can try either at no cost before committing.

What is Memcached best used for?

Memcached is most often used for caching expensive database query results to cut load, session storage where losing sessions on restart is acceptable, fronting an api whose responses are costly and change slowly. Of those, caching expensive database query results to cut load and session storage where losing sessions on restart is acceptable are not what Vitess is typically brought in for.

What can Memcached do that Vitess cannot?

Memcached covers In-memory key-value cache, Multithreaded, Client-side sharding, Predictable memory use. Vitess covers Horizontal Sharding, Connection Pooling, Query Routing, Online Schema Changes.

The short version

Each has a real cost: Memcached no persistence at all: restart a node and its cache is gone, which every design must assume; Vitess vTGate scatter queries without sharding key incur significant performance penalties
They diverge on capability: Memcached covers In-memory key-value cache, Vitess covers Horizontal Sharding.

Where each one falls short

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

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

Vitess

VTGate scatter queries without sharding key incur significant performance penalties
Foreign key constraints not enforced across shards, requiring application-level integrity handling
Single primary per keyspace limits multi-region write capabilities
Distributed transactions without proper sharding key routing suffer performance degradation

Answered from the vendors’ own pages

Memcached: Is Memcached free?

Yes, open source with no licence fee.

Vitess: Is Vitess free to use?

Yes. Vitess is completely free and open source under the Apache 2.0 license. It is a graduated CNCF project with no licensing costs or pricing tiers.

Memcached: Memcached or Redis?

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.

Vitess: What databases does Vitess support?

Vitess supports MySQL and MariaDB as backend databases. It acts as a middleware layer that adds sharding and orchestration capabilities on top of these databases.

Source

Memcached: Does Memcached persist data?

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

Vitess: Does Vitess require Kubernetes to run?

No. Vitess can run on Kubernetes using the Vitess Operator, but it can also be deployed on traditional infrastructure. Kubernetes integration is optional and provides additional automation benefits.

Source

Vitess: How does Vitess handle cross-shard transactions?

Vitess supports distributed transactions across shards, but they require queries to be routed through the sharding key. Transactions without a proper sharding key can result in slower performance.

Source

Vitess: Does Vitess enforce foreign key constraints?

Vitess does not enforce foreign key constraints across shards by default. Referential integrity must be managed at the application layer, though per-database support can be enabled with limitations.
