William FH	b7b62e29fb	community[patch], mongodb[patch]: Stop spamming SIMD import warnings (#19531) ... If you use an embedding dist function in an eval loop, you get warned every time. Would prefer to just check once and forget about it. --------- Co-authored-by: Bagatur <baskaryan@gmail.com>	4 months ago
Ash Vardanian	d01bad5169	core[patch]: Convert SimSIMD back to NumPy (#19473) ... This patch fixes the #18022 issue, converting the SimSIMD internal zero-copy outputs to NumPy. I've also noticed, that oftentimes `dtype=np.float32` conversion is used before passing to SimSIMD. Which numeric types do LangChain users generally care about? We support `float64`, `float32`, `float16`, and `int8` for cosine distances and `float16` seems reasonable for practically any kind of embeddings and any modern piece of hardware, so we can change that part as well 🤗	4 months ago
Jib	f8078e41e5	mongodb[patch]: Added scoring threshold to caching (#19286) ... ## Description Semantic Cache can retrieve noisy information if the score threshold for the value is too low. Adding the ability to set a `score_threshold` on cache construction can allow for less noisy scores to appear. - [x] **Add tests and docs** 1. Added tests that confirm the `score_threshold` query is valid. - [x] **Lint and test**: Run `make format`, `make lint` and `make test` from the root of the package(s) you've modified. See contribution guidelines for more: https://python.langchain.com/docs/contributing/ --------- Co-authored-by: Erick Friis <erick@langchain.dev>	4 months ago
Jib	516cc44b3f	langchain-mongodb: [test-fix] add explicit index_name setting on test vector creation (#19245) ... - **Description:** Tests fail to do value lookup because it does not specify the index name - **Issue:** the issue # Failing integration test - [x] **Add tests and docs**: Tests now pass - [x] **Lint and test**: Run `make format`, `make lint` and `make test` from the root of the package(s) you've modified.

Jib	ec026004cb	mongodb[patch]: Remove in-memory cache from cache abstractions (#18987) ... ## Description * In memory cache easily gets out of sync with the server cache, so we will remove it entirely to reduce the issues around invalidated caches. ## Dependencies None - [x] If you're adding a new integration, please include 1. a test for the integration, preferably unit tests that do not rely on network access, 2. an example notebook showing its use. It lives in `docs/docs/integrations` directory. - [x] **Lint and test**: Run `make format`, `make lint` and `make test` from the root of the package(s) you've modified.

Jib	866d6408af	mongodb[patch]: Remove embedding retrieval from mongodb payload (#19035) ... ## Description Returning the embedding is not necessary in the vector search functionality unless specified as a debugging step. This change defaults the behavior such that the server _only_ returns the embedding key if explicitly requested, such as in the case of `max_marginal_relevance_search`. - [x] **Add tests and docs**: If you're adding a new integration, please include * Added `test_from_documents_no_embedding_return` - [x] **Lint and test**: Run `make format`, `make lint` and `make test` from the root of the package(s) you've modified.

Jib	f92f7d2e03	mongodb[minor]: Add MongoDB LLM Cache (#17470) ... # Description - **Description:** Adding MongoDB LLM Caching Layer abstraction - **Issue:** N/A - **Dependencies:** None - **Twitter handle:** @mongodb Checklist: - [x] PR title: Please title your PR "package: description", where "package" is whichever of langchain, community, core, experimental, etc. is being modified. Use "docs: ..." for purely docs changes, "templates: ..." for template changes, "infra: ..." for CI changes. - Example: "community: add foobar LLM" - [x] PR Message (above) - [x] Pass lint and test: Run `make format`, `make lint` and `make test` from the root of the package(s) you've modified to check that you're passing lint and testing. See contribution guidelines for more information on how to write/run tests, lint, etc: https://python.langchain.com/docs/contributing/ - [ ] Add tests and docs: If you're adding a new integration, please include 1. a test for the integration, preferably unit tests that do not rely on network access, 2. an example notebook showing its use. It lives in `docs/docs/integrations` directory. Additional guidelines: - Make sure optional dependencies are imported within a function. - Please do not add dependencies to pyproject.toml files (even optional ones) unless they are required for unit tests. - Most PRs should not touch more than one package. - Changes should be backwards compatible. - If you are adding something to community, do not re-import it in langchain.

Jib	72bfc1d3db	mongodb[minor]: MongoDB Partner Package -- Porting MongoDBAtlasVectorSearch (#17652) ... This PR migrates the existing MongoDBAtlasVectorSearch abstraction from the `langchain_community` section to the partners package section of the codebase. - [x] Run the partner package script as advised in the partner-packages documentation. - [x] Add Unit Tests - [x] Migrate Integration Tests - [x] Refactor `MongoDBAtlasVectorStore` (autogenerated) to `MongoDBAtlasVectorSearch` - [x] ~Remove~ deprecate the old `langchain_community` VectorStore references. ## Additional Callouts - Implemented the `delete` method - Included any missing async function implementations - `amax_marginal_relevance_search_by_vector` - `adelete` - Added new Unit Tests that test for functionality of `MongoDBVectorSearch` methods - Removed [`del res[self._embedding_key]`](e0c81e1cb0/libs/community/langchain_community/vectorstores/mongodb_atlas.py (L218)) in `_similarity_search_with_score` function as it would make the `maximal_marginal_relevance` function fail otherwise. The `Document` needs to store the embedding key in metadata to work.
