Chroma is an open-source vector database. MantrixFlow can write to Chroma when your data includes an embedding column. Produce embeddings upstream before writing to this destination.

​
Prerequisites

You need a Chroma instance (self-hosted or Chroma Cloud) and the connection URL. Chroma can run locally or as a server.

​

2. Collection Name

Enter the collection name. The collection is created if it does not exist, with dimensions from your embedding column.

Data Requirements

  • Embedding column — Vector data. Dimensions are inferred from the first batch.
  • Upsert key — Used as the document ID for upsert operations. Must be unique per vector.
