Browse Source 
This reverts commit a547c523c2 or #2281

The current implementation can cause panics and performance degradation.
I will bring this back with more testing in

## Summary by CodeRabbit

- **Documentation**
- Enhanced clarity on read consistency settings with updated
descriptions and default behavior.
- Removed outdated warnings about eventual consistency from the
troubleshooting guide.

- **Refactor**
- Streamlined the handling of the read consistency interval across
integrations, now defaulting to "None" for improved performance.
  - Simplified internal logic to offer a more consistent experience.

- **Tests**
- Updated test expectations to reflect the new default representation
for the read consistency interval.
- Removed redundant tests related to "no consistency" settings for
streamlined testing.
