Hi @nubufi! I'm Dosu and I’m helping the llama_index team.

The reason you can't install both llama-index-storage-chat-store-dynamodb and llama-index-vector-stores-s3 together is due to incompatible version requirements for shared dependencies, specifically boto3 and llama-index-core. The S3 vector store requires a newer boto3 (>=1.39.8) and an older llama-index-core (<0.13), while the DynamoDB chat store requires aioboto3 (which pins boto3 to older, narrower ranges) and a newer llama-index-core (>=0.13.0,<0.15). These constraints do not overlap, so dependency resolution fails and you can't install both at the same time with the current versions and constraints.

There are no open issues or merged pull requests addressing this incompatibility, and the S3 vector store integration does not appear to be maintained in the main LlamaIndex repository, so no immediate fix is available. If you need both functionalities, you may need to use separate environments or consider alternative storage/vector backends until the dependencies are aligned in future releases. For reference, you can see the dependency requirements for the DynamoDB integration in its pyproject.toml.

To reply, just mention @dosu.
