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.

"DD_TRACE_DALLI_ANALYTICS_SAMPLE_RATE"
ENV_COMMAND_ENABLED =

DEV: This is named *_MEMCACHED_* because the spans it refer to are memcached.* and this variable DEV: is a global flag that affects all memcached spans generated by any Datadog product.
