Remarks
This strategy bridges the IChatReducer abstraction from Microsoft.Extensions.AI into the compaction pipeline. It collects the currently included messages from the CompactionMessageIndex, passes them to the reducer, and rebuilds the index from the reduced message list when the reducer produces fewer messages.
The CompactionTrigger controls when reduction is attempted. Use CompactionTriggers for common trigger conditions such as token or message thresholds.
Use this strategy when you have an existing IChatReducer implementation (such as MessageCountingChatReducer) and want to apply it as part of a CompactionStrategy pipeline or as an in-run compaction strategy.
Constructors
| Name | Description |
|---|---|
| ChatReducerCompactionStrategy(IChatReducer, CompactionTrigger) |
Initializes a new instance of the ChatReducerCompactionStrategy class. |
Properties
| Name | Description |
|---|---|
| ChatReducer |
Gets the chat reducer used to reduce messages. |
| Target |
Gets the target predicate that controls when compaction stops.
Strategies re-evaluate this after each incremental exclusion and stop when it returns |
| Trigger |
Gets the trigger predicate that controls when compaction proceeds. (Inherited from CompactionStrategy) |
Methods
| Name | Description |
|---|---|
| CompactAsync(CompactionMessageIndex, ILogger, CancellationToken) |
Evaluates the Trigger and, when it fires, delegates to CompactCoreAsync(CompactionMessageIndex, ILogger, CancellationToken) and reports compaction metrics. (Inherited from CompactionStrategy) |
| CompactCoreAsync(CompactionMessageIndex, ILogger, CancellationToken) |
Applies the strategy-specific compaction logic to the specified message index. (Inherited from CompactionStrategy) |
Extension Methods
| Name | Description |
|---|---|
| AsChatReducer(CompactionStrategy) |
Returns an IChatReducer that applies this CompactionStrategy to reduce a list of messages. |
