Overview

Dalli integration constants

Constant Summary collapse

ENV_ENABLED = DEV: Even though this is the dalli integration, all spans are named ‘memcached.*`. DEV: This happens because such spans have special treatment in backend, with memcached-specific handling. DEV: If add support for the `memcached` gem (not popular as of 2023), we’ll have issues with span naming DEV: conflicts.
