existsById fetches entire JSON instead of using key existence check #657
Description
version- redis-om-spring:1.0.0
Currently, calling existsById(id) on a RedisDocumentRepository generates a JSON.GET $ command to check if the document exists. While this works, it fetches the entire JSON document from Redis.
Problem:
If the JSON document is large, this approach is inefficient: it unnecessarily transfers the full payload over the network to check for existence. A simple EXISTS command would be much faster and lighter.
Expected behavior:
existsById(id) should internally use EXISTS (or an equivalent lightweight check) instead of fetching the full JSON content.
Impact:
- Reduces network overhead for large documents.
- Improves performance for existence checks in repositories storing big JSON objects.
