HeavyDB, formerly known as OmniSciDB, is an open-source SQL-based, relational, columnar database engine designed specifically for handling massive datasets efficiently. By utilizing the immense power of modern CPUs and GPUs, HeavyDB queries datasets with billions of rows in mere milliseconds.
Why Choose HeavyDB?
- High Performance: No need for excessive indexing or pre-aggregation. HeavyDB’s innovative design harnesses parallelism, leading to astonishing speed in data processing.
- Versatility: It runs effectively on both CPU-only systems and hybrid CPU/GPU environments.
- Smart Caching: HeavyDB optimizes processing through multi-tiered caching between storage, CPU memory, and GPU memory.
Installation Guide
To get HeavyDB up and running, follow these simple steps:
- Choose your distribution: HeavyDB provides pre-built binaries for Linux stable releases, including CentOS and Ubuntu.
- Download the Package: You can download the appropriate binary for your system from these links:
- CentOS CPU: RPM Package
- CentOS GPU: RPM Package
- Ubuntu CPU: DEB Package
- Ubuntu GPU: DEB Package
- Tarball CPU: Download
- Tarball GPU: Download
- Installation: Use the provided package managers (YUM or APT) or manually extract and install the tarball.
Using HeavyDB
Once installed, start the HeavyDB server by executing the following commands in your terminal:
mkdir data
.bin/initdb data
.bin/heavydb
The startheavy script can also help initialize and start the database effortlessly.
Understanding HeavyDB through Analogy
Imagine HeavyDB as a highly efficient library. In this library:
- The shelves are organized in a columnar format, where books (data) are stored by topics (columns) instead of the traditional row-wise method.
- When researchers (queries) come in with questions about millions of books, they don’t need to check the entire library for answers. Instead, they head straight to the relevant shelves, finding their answers in the nick of time.
- Some books are available in multiple languages (pre-aggregated) but without the complexity of needing to search through different sections. The library (HeavyDB) smartly caches popular books (data) for quick access, enhancing the experience.
Troubleshooting
If you encounter issues during the installation or usage of HeavyDB, consider the following:
- Check Dependencies: Ensure all dependencies listed in the README are met.
- Environment Variables: Configure CUDA and mapd-deps lib directories correctly.
- Access Forums: Utilize the HEAVY.AI Community Forum for discussions and solutions.
