DreamDB Python SDK
Python bindings for the DreamDB multimodal versioned data lake — image + audio + text + embeddings + scalar metadata on content-addressed object storage, with vector and metadata filters for ML training pipelines.
Quick start
import dreamdb as vd
# Schema
schema = vd.Schema()
schema.add_image("image", mime="jpeg")
schema.add_embedding("embedding", dim=128)
schema.add_scalar_categorical("label")
# Create against any backend (file://, http(s)://, memory://)
ds = vd.Dataset.create(
"my-dataset",
schema,
backend="file:///tmp/my-ds",
)
# Append a batch of samples (each a dict)
ds.append_many([
{"image": open("cat.jpg", "rb").read(),
"embedding": [0.1, 0.2, ...],
"label": "cat"},
# ...
])
# Filter::Vector + Filter::Where (And)
batches = ds.iter_vector(
field="embedding",
query=[0.1, 0.2, ...],
top_k=10,
batch_size=4,
where_eq={"label": "cat"},
)
for batch in batches:
images = batch["image"] # list[bytes]
embeds = batch["embedding"] # list[list[float]]
labels = batch["label"] # list[str]
Build from source
pip install maturin
cd dreamdb-dataset-python
maturin develop --release
This produces the dreamdb package installed into the
current virtualenv. Importing it gives the Schema and Dataset
classes shown above.
