A Comprehensive Guide to DeepSeek Smallpond

DeepSeek AI's Smallpond: A Lightweight Framework for Distributed Data Processing

Building on the success of DeepSeek R1, DeepSeek AI introduces Smallpond, a streamlined data processing framework designed for efficient handling of massive datasets. This innovative solution combines the speed of DuckDB for SQL analytics with the high-performance distributed storage capabilities of 3FS, enabling the processing of petabyte-scale data with minimal infrastructure overhead. Smallpond simplifies data processing for AI and big data applications, eliminating the need for complex setups and long-running services. This article explores Smallpond's features, components, and applications, providing a practical guide to its usage.

What is DeepSeek Smallpond?

Smallpond, an open-source project released February 28, 2025, during DeepSeek's Open Source Week, is a lightweight framework extending the power of DuckDB, a high-performance in-process analytical database, into distributed environments. By integrating with 3FS (Fire-Flyer File System), Smallpond offers a scalable solution for petabyte-scale data without the complexities of traditional big data platforms like Apache Spark. It's targeted at data engineers and scientists seeking efficient and easy-to-use tools for distributed analytics.

Key Features:

• High Performance: Leverages DuckDB's SQL engine and 3FS's high throughput.
• Scalability: Processes petabyte-scale data across distributed nodes using manual partitioning.
• Simplicity: Minimal setup, eliminating complex dependencies and long-running services.
• Flexibility: Supports Python (3.8–3.12) and integrates with Ray for parallel processing.
• Open Source: MIT-licensed, encouraging community contributions.

Core Components:

• DuckDB: An embedded, in-process SQL OLAP database optimized for analytical workloads. Smallpond extends its capabilities to distributed systems.
• 3FS (Fire-Flyer File System): DeepSeek's distributed file system designed for AI and HPC, using modern SSDs and RDMA networking for high throughput and low latency. It prioritizes random reads.
• Integration: Smallpond uses DuckDB for computation and 3FS for storage. Data (in Parquet format) is manually partitioned and processed in parallel across nodes using DuckDB instances coordinated by Ray.

Getting Started with Smallpond:

Installation: Smallpond (currently Linux only) is installed via pip. Python 3.8–3.11 and a compatible 3FS cluster (or local filesystem for testing) are required.

pip install smallpond
pip install "smallpond[dev]" # Optional development dependencies
pip install 'ray[default]' # Ray Clusters

3FS installation involves cloning and building from the GitHub repository (see 3FS documentation for detailed instructions).

Environment Setup:

Initialize Ray for 3FS clusters:

ray start --head --num-cpus=<num_cpus> --num-gpus=<num_gpus></num_gpus></num_cpus>

Initialize Smallpond (replace with your Ray address and 3FS endpoint if applicable):

import smallpond
sp = smallpond.init(data_root="Path/to/local/Storage", ray_address="192.168.214.165:6379") # Local filesystem
# sp = smallpond.init(data_root="3fs://cluster_endpoint", ray_address="...") # 3FS cluster

Data Ingestion and Preparation:

Smallpond primarily supports Parquet.

# Read Parquet
df = sp.read_parquet("data/input.prices.parquet")
# Process data (example)
df = df.map("price > 100")
# Write data
df.write_parquet("data/output/filtered.prices.parquet")

Partitioning strategies include by file count, rows, or column hash using df.repartition().

API Reference: The high-level API simplifies data manipulation. A lower-level API provides direct access to DuckDB and Ray for advanced users. (Detailed function descriptions are provided in the original article).
