Is Memcached or Readyset better?

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

Which is cheaper, Memcached or Readyset?

Memcached starts at Free and Readyset at Free.

Does Memcached or Readyset run on more platforms?

Memcached runs on Linux, macOS, Windows, Docker, Self-hosted. Readyset runs on Cloud, Self-Hosted.

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 Readyset is typically brought in for.

What can Memcached do that Readyset cannot?

Memcached covers In-memory key-value cache, Multithreaded, Client-side sharding, Predictable memory use. Readyset covers Automatic Query Optimization, SQL-Level Caching, Live Incremental Updates, Zero-Touch Integration.

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; Readyset pricing requires contacting sales team, making cost planning difficult
They diverge on capability: Memcached covers In-memory key-value cache, Readyset covers Automatic Query Optimization.

Where they differ

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

Readyset

Pricing requires contacting sales team, making cost planning difficult
Specific pricing tiers not disclosed publicly
Requires cache size estimation for cost calculation
Limited to read query caching, does not address write performance

Answered from the vendors’ own pages

Memcached: Is Memcached free?

Yes, open source with no licence fee.

Readyset: Do I need to change my application code?

No, Readyset integrates transparently through query interception with zero code changes or schema modifications required.

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.

Readyset: Is there a free trial?

Yes, Readyset offers a free 7-day trial that lets you test different cache sizes before committing to a paid plan.

Source

Memcached: Does Memcached persist data?

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

Readyset: How does Readyset pricing work?

Readyset is available as a monthly or annual subscription charged based on the size of cache you need. Contact [email protected] for specific pricing.
