Detailed Description
Interface for handling updates from LaunchDarkly.
Implementations must be thread-safe. A data source calls these from whichever thread it runs on, concurrently with flag evaluation and listener registration on the application's threads.
Member Function Documentation
◆ Apply()
|
pure virtual |
Applies a changeset as a single unit. Unlike Upsert, this path does not order or reject updates by version. FDv2 reserves the per-flag version for event tracking and manages payload consistency through selectors instead.
- Parameters
-
from_cache Whether the changeset was loaded from the local cache, in which case it is not written back to it.
Implemented in launchdarkly::client_side::flag_manager::FlagUpdater, and launchdarkly::client_side::flag_manager::FlagPersistence.
The documentation for this class was generated from the following file:
- src/data_sources/data_source_update_sink.hpp
