Features

• Feature Flag Management - Provides utilities for programmatically controlling feature availability and configuration through flag toggles.
• Feature Flags - Implements dynamic feature toggles in Elixir applications to control code paths without deployments.
• Feature Flags - Provides a library for managing runtime feature toggles using actor, group, and percentage-based rules.
• App or Feature Disablings - Checks whether a specific feature is currently enabled for the application or for a particular user or group at runtime.
• Access Rule Evaluators - Evaluates access rules for individual entities or groups to determine feature availability.
• Data Persistence Management - Manages the lifecycle and scheduling of data writing operations to ensure reliable storage.
• Repository Definitions - Maps application modules to underlying data stores using adapters to manage connections and lifecycle processes.
• Pluggable Storage Backends - Abstracts storage backends behind a common interface to allow flag data to reside in various databases or caches.
• Runtime Feature Toggles - Enables or disables functionality at runtime using boolean, actor-specific, group-based, or percentage-based rules.
• Persistence Adapters - Stores feature flag configurations in external databases or caches using pluggable adapters.
• State Synchronization - Propagates feature flag changes across distributed application nodes to ensure consistent state across a cluster.
• Cluster State Synchronization - Propagates flag changes across distributed application instances using messaging mechanisms to ensure consistent behavior throughout a cluster.
• Group-Based Access Controls - Restricts feature availability based on membership in defined user or entity groups.
• Actor-Based Access Controls - Enables or disables features for specific users by evaluating access rules against individual actors.
• Distributed State Synchronization - Propagates configuration changes across multiple application nodes using messaging backends to maintain consistent state in a cluster.
• Feature Removals - Allows deletion of specific gate configurations or entire flag definitions to revert application functionality to its default state.
• Transactional Grouping - Groups multiple database operations into a single atomic transaction to ensure all-or-nothing completion.
• Data Access and Querying - Provides interfaces and abstraction layers used to interact with and retrieve data from storage systems.
• Distributed State Synchronizers - Propagates configuration changes across distributed nodes to maintain consistent application state.
• Distributed Cache Synchronizers - Synchronizes cache states across distributed application nodes using messaging backends to ensure consistent configuration.
• In-Memory Caches - Maintains local copies of flag configurations to minimize latency and reduce database load during frequent feature state checks.
• Storage Backend Adapters - Provides interfaces for swapping default storage mechanisms with custom persistent backends for flag data.
• Struct-to-Table Mappings - Provides declarative mappings that define how application structs correspond to database table columns and types.
• Feature Flag Toggles - Synchronizes feature flag states across distributed clusters to ensure consistent behavior.
• Administrative Dashboards - Provides a web-based graphical interface for managing flag lifecycles and rules without code changes.
• Performance Monitors - Evaluates the latency and throughput of flag lookups to ensure minimal overhead during application runtime.
• Persistence Architectures - Stores toggle configurations in external databases to maintain state across application restarts.
• Telemetry Instrumentation - Provides telemetry instrumentation to monitor flag activity and performance metrics during runtime.
• Custom Event Handlers - Provides extensible logic for processing and responding to specific system events through custom plugins.
• Telemetry Event Dispatchers - Routes instrumentation events to registered diagnostic collectors for monitoring system operations.
• Runtime Behavior Controllers - Adjusts system functionality dynamically by evaluating gate conditions and rules during application execution.
• Flag Change Webhooks - Sends notifications or triggers when a feature flag changes, enabling consistent state across a cluster.
• Administrative Dashboards - Offers a graphical user interface for managing and toggling feature flags to control application behavior.
• Atomic Rule Update Mechanisms - Groups multiple rule modifications into single operations to ensure data integrity and consistent behavior during runtime configuration changes.
• Actor Evaluation Protocols - Uses defined interfaces to identify and match specific users or groups against complex feature flag rules at runtime.
• Automatic Span Timing - Measures duration of named code blocks and automatically includes elapsed time in telemetry events.
• Telemetry and Monitoring Agents - Tracks feature usage and system performance by emitting diagnostic events and measuring lookup latency.
• Application Event Dispatching - Provides systems for routing high-level application events to allow external instrumentation.
• Web-Based Control Panels - Provides a web-based control panel for managing and toggling feature flags without modifying underlying application code.
