DingoDB

DingoDB is a distributed multi-modal vector database. It combines the features of a data lake and a vector database, allowing for the storage of any type of data (key-value, PDF, audio, video, etc.) regardless of its size. Utilizing DingoDB, you can construct your own Vector Ocean (the next-generation data architecture following data warehouse and data lake, as introduced by DataCanvas). This enables the analysis of both structured and unstructured data through a singular SQL with exceptionally low latency in real time.

Key Features

As a Distributed Vector Database for Any Data

  1. Provides comprehensive data storage solutions, accommodating a wide range of data types including but not limited to embeddings, audio files, text, videos, images, PDFs, and annotations.
  2. Facilitates efficient querying and vector searching with minimal latency using a singular SQL approach.
  3. Employs a hybrid search mechanism that caters to both structured and unstructured data, supporting operations like metadata querying and vector querying.
  4. Possesses the ability to dynamically ingest data and construct corresponding indexes in real time, promoting operational efficiency.

As a Distributed Relation database

  1. MySQL Compatibility Built upon the acclaimed Apache Calcite SQL engine, DingoDB is capable of parsing, optimizing, and executing standard SQL statements, and can handle parts of TPC-H and TPC-DS(See TPC) queries. Compliant with MySQL Shell and MySQL-JDBC-Driver Client, it offers seamless integration with web services, BI tools, and more.
  2. Supports High Frequency Write Operations: With the use of RAFT and the log-structured key-value storage RocksDB., DingoDB can handle high-frequency INSERT, UPDATE, DELETE, and short-QUERY operations while maintaining strong data consistency.
  3. Facilitates Point Queries and Multi-dimensional Analysis Simultaneously: DingoDB can push down expressions to accelerate queries and quickly carry out multi-dimensional analysis with low latency.
  4. Distributed Storage Capabilities As a distributed storage engine, DingoDB has the capacity to store vast amounts of data. It allows for easy horizontal scaling operations on clusters as data scale increases.
  5. High Data Reliability and Recovery: Designed based on Raft, DingoDB provides a multi-replicated management mechanism, ensuring extraordinarily high data reliability. It can maintain high data consistency even in the event of disk or machine failures and offers a swift automatic recovery mechanism.

Developing DingoDB

We recommend IntelliJ IDEA to develop the DingoDB codebase. Minimal requirements for an IDE are:

  • Support for Java
  • Support for Gradle

How to make a clean pull request

  • Create a personal fork of dingo on GitHub.
  • Clone the fork on your local machine. Your remote repo on GitHub is called origin.
  • Add the original repository as a remote called upstream.
  • If you created your fork a while ago be sure to pull upstream changes into your local repository.
  • Create a new branch to work on. Branch from develop.
  • Implement/fix your feature, comment your code.
  • Follow the code style of Google code style, including indentation.
  • If the project has tests run them!
  • Add unit tests that test your new code.
  • In general, avoid changing existing tests, as they also make sure the existing public API is unchanged.
  • Add or change the documentation as needed.
  • Squash your commits into a single commit with git's interactive rebase.
  • Push your branch to your fork on GitHub, the remote origin.
  • From your fork open a pull request in the correct branch. Target the Dingo's develop branch.
  • Once the pull request is approved and merged you can pull the changes from upstream to your local repo and delete your branch.
  • Last but not least: Always write your commit messages in the present tense. Your commit message should describe what the commit, when applied, does to the code – not what you did to the code.

IntelliJ IDEA

The IntelliJ IDE supports Java and Gradle out of the box. Download it at IntelliJ IDEA website.
