The doc reviewer will arrange for an editorial review. |
- Add long-term memory APIs: search, update, delete - Add memory history APIs: search, delete - Add general memory APIs: get, update, delete, search by type - Update add-memory API to include data type memory and structured data - Update index with complete API structure - Support for conversation memory, data memory, and trace data - Include namespace-based organization and tagging system - Remove experimental warning as agentic memory is GA in 3.3 Signed-off-by: Dhrubo Saha <[email protected]>

Hey @dhrubo-os , let me know when this PR is ready for doc review. We have 3 days left before the release. |
- Remove redundant API files in favor of unified memory APIs - Delete legacy files: delete-long-term-memory.md, delete-memory-history.md, search-long-term-memory.md, search-memory-history.md, update-long-term-memory.md, search-memory.md, delete-memory.md, update-memory.md, get-memory.md - Enhance unified APIs with comprehensive examples for all memory types (sessions, working, long-term, history) - Add metadata field documentation to add-memory.md and get-memory-by-type.md - Update response examples and field documentation with actual API responses - Update index.md to reflect clean unified API structure - Fix memory type parameter names (sessions vs session) for consistency Signed-off-by: Dhrubo Saha <[email protected]>
- Add missing update-memory-container.md and search-memory-container.md files - Update create-memory-container.md with advanced features from Postman collection: * Multiple strategy support (SEMANTIC, USER_PREFERENCE, SUMMARY) * Strategy configuration with llm_result_path * Index configuration (index_prefix, use_system_index) * Remove experimental warning (GA in 3.3) - Remove experimental feature reference from index.md - All APIs now match actual implementation from Postman collection Signed-off-by: Dhrubo Saha <[email protected]>
- Add default llm_result_path value: $.output.message.content[0].text (Bedrock Converse format) - Document LLM connector requirement for system_prompt and user_prompt parameters - Reference ml-commons PR opensearch-project#4283 for standardized connector format - Clarify that default is optimized for Bedrock Converse API Signed-off-by: Dhrubo Saha <[email protected]>
Yes please start reviewing the PR. Thanks |

This API supports two parameters
delete_all_memories: control delete all memory indices or not when delete container. Default isfalse. That means the memory index (sessions/working/long-term/history) will not be deleted when delete containerdelete_memories: array of memory types , defines deleting which memory index when delete container. Default is empty array. User can set as "delete_memories=sessions,working"
