Q: Go-rejson vs using native go-redis JSON commands: which should I choose?

Go-rejson provides a higher-level, type-safe abstraction over ReJSON, ideal for complex JSON operations. If you only need basic JSON support or prefer direct control, native commands might suffice but lack type safety.

Q: How to query nested JSON fields with go-rejson?

Use JSONPath-like syntax in commands like JSONGet, such as '.field.subfield', to access nested elements directly. This mirrors ReJSON's functionality and avoids manual traversal in Go code.

Q: What happens if I use go-rejson without the ReJSON module?

Commands will fail because Redis won't recognize JSON-specific operations. You must have the ReJSON module loaded in Redis; otherwise, go-rejson is unusable for JSON storage and retrieval.

Q: Are there performance benchmarks for go-rejson with large documents?

The README doesn't provide benchmarks, but it notes efficient binary tree storage. For large documents, performance depends on Redis and ReJSON's implementation; test with your data to gauge impact on memory and latency.

Question 1

How do I set up go-rejson with the redigo client?

Accepted Answer

Install via 'go get github.com/nitishm/go-rejson/v4', then use rh.SetRedigoClient(conn) after establishing a Redis connection. The README includes a full example with error handling and cleanup.

Question 2

Is go-rejson compatible with Redis 7?

Accepted Answer

Compatibility depends on the ReJSON module version. Go-rejson only supports ReJSON <=1.0.8, so you must ensure that version is available for Redis 7, which may not be the case with newer module releases.
