module NewRelic::Agent::Instrumentation::ActiveRecordHelper
Constants
- ACTIVE_RECORD
- ACTIVE_RECORD_DEFAULT_PRODUCT_NAME
- EMPTY
- OPERATION_NAMES
These are used primarily to optimize and avoid allocation on well known operations coming in. Anything not matching the list is fine, it just needs to get downcased directly for use.
- OTHER
- PRODUCT_NAMES
- SPACE
