Stefano Lottini	040597e832	community: init signature revision for Cassandra LLM cache classes + small maintenance (#17765 ) This PR improves on the `CassandraCache` and `CassandraSemanticCache` classes, mainly in the constructor signature, and also introduces several minor improvements around these classes. ### Init signature A (sigh) breaking change is tentatively introduced to the constructor. To me, the advantages outweigh the possible discomfort: the new syntax places the DB-connection objects `session` and `keyspace` later in the param list, so that they can be given a default value. This is what enables the pattern of _not_ specifying them, provided one has previously initialized the Cassandra connection through the versatile utility method `cassio.init(...)`. In this way, a much less unwieldy instantiation can be done, such as `CassandraCache()` and `CassandraSemanticCache(embedding=xyz)`, everything else falling back to defaults. A downside is that, compared to the earlier signature, this might turn out to be breaking for those doing positional instantiation. As a way to mitigate this problem, this PR typechecks its first argument trying to detect the legacy usage. (And to make this point less tricky in the future, most arguments are left to be keyword-only). If this is considered too harsh, I'd like guidance on how to further smoothen this transition. Our plan is to make the pattern of optional session/keyspace a standard across all Cassandra classes, so that a repeatable strategy would be ideal. A possibility would be to keep positional arguments for legacy reasons but issue a deprecation warning if any of them is actually used, to later remove them with 0.2 - please advise on this point. ### Other changes - class docstrings: enriched, completely moved to class level, added note on `cassio.init(...)` pattern, added tiny sample usage code. - semantic cache: revised terminology to never mention "distance" (it is in fact a similarity!). Kept the legacy constructor param with a deprecation warning if used. - `llm_caching` notebook: uniform flow with the Cassandra and Astra DB separate cases; better and Cassandra-first description; all imports made explicit and from community where appropriate. - cache integration tests moved to community (incl. the imported tools), env var bugfix for `CASSANDRA_CONTACT_POINTS`. --------- Co-authored-by: Erick Friis <erick@langchain.dev>	4 months ago

Eugene Yurtsev	5c2cfabec6	core[minor]: Add v2 implementation of astream events (#21638 ) This PR introduces a v2 implementation of astream events that removes intermediate abstractions and fixes some issues with v1 implementation. The v2 implementation significantly reduces relevant code that's associated with the astream events implementation together with overhead. After this PR, the astream events implementation: - Uses an async callback handler - No longer relies on BaseTracer - No longer relies on json patch As a result of this re-write, a number of issues were discovered with the existing implementation. ## Changes in V2 vs. V1 ### on_chat_model_end `output` The outputs associated with `on_chat_model_end` changed depending on whether it was within a chain or not. As a root level runnable the output was: ```python "data": {"output": AIMessageChunk(content="hello world!", id='some id')} ``` As part of a chain the output was: ``` "data": { "output": { "generations": [ [ { "generation_info": None, "message": AIMessageChunk( content="hello world!", id=AnyStr() ), "text": "hello world!", "type": "ChatGenerationChunk", } ] ], "llm_output": None, } }, ``` After this PR, we will always use the simpler representation: ```python "data": {"output": AIMessageChunk(content="hello world!", id='some id')} ``` NOTE Non chat models (i.e., regular LLMs) are still associated with the more verbose format. ### Remove some `_stream` events `on_retriever_stream` and `on_tool_stream` events were removed -- these were not real events, but created as an artifact of implementing on top of astream_log. The same information is already available in the `x_on_end` events. ### Propagating Names Names of runnables have been updated to be more consistent ```python model = GenericFakeChatModel(messages=infinite_cycle).configurable_fields( messages=ConfigurableField( id="messages", name="Messages", description="Messages return by the LLM", ) ) ``` Before: ```python "name": "RunnableConfigurableFields", ``` After: ```python "name": "GenericFakeChatModel", ``` ### on_retriever_end on_retriever_end will always return `output` which is a list of documents (rather than a dict containing a key called "documents") ### Retry events Removed the `on_retry` callback handler. It was incorrectly showing that the failed function being retried has invoked `on_chain_end` https://github.com/langchain-ai/langchain/pull/21638/files#diff-e512e3f84daf23029ebcceb11460f1c82056314653673e450a5831147d8cb84dL1394	4 months ago
