Question 1

How to switch from Redis to Consul using gokv?

Accepted Answer

Change the import from github.com/philippgille/gokv/redis to github.com/philippgille/gokv/consul, update the options and client initialization, but keep the same Store interface calls—no logic changes needed, as shown in the Usage examples.

Question 2

gokv vs direct database client: which is better for performance?

Accepted Answer

Native clients often outperform gokv due to fewer abstraction layers, but gokv's overhead is minimal for most use cases; choose it for flexibility across backends, not raw speed.

Question 3

Does gokv support key expiration or TTL for caching?

Accepted Answer

Not directly in the interface; some backends like Redis or Memcached can be configured separately via their options, but you lose portability if relying on such features.

Question 4

How to handle custom struct marshaling in gokv?

Accepted Answer

Implement methods like MarshalJSON or GobEncode for your structs, as detailed in the Value Types section, to control serialization and include unexported fields.

Question 5

Is gokv good for high-throughput microservices?

Accepted Answer

It can work, but the abstraction may add latency; benchmark with your specific backend, as the README admits performance depends on marshaling formats and implementation details.

Question 6

What happens if a backend isn't supported in gokv?

Accepted Answer

You can write your own Store implementation, following the simple interface, or request it via GitHub issues—the project encourages contributions, but coverage gaps exist, like missing Azure Cosmos DB.
