The Universal Storage Engine

TileDB is a powerful engine for storing and accessing dense and sparse multi-dimensional arrays, which can help you model any complex data efficiently. It is an embeddable C++ library that works on Linux, macOS, and Windows. It is open-sourced under the permissive MIT License, developed and maintained by TileDB, Inc. To distinguish this project from other TileDB offerings, we often refer to it as TileDB Embedded.

TileDB includes the following features:

  • Support for both dense and sparse arrays
  • Support for dataframes and key-value stores (via sparse arrays)
  • Cloud storage (AWS S3, Google Cloud Storage, Azure Blob Storage)
  • Chunked (tiled) arrays
  • Multiple compression, encryption and checksum filters
  • Fully multi-threaded implementation
  • Parallel IO
  • Data versioning (rapid updates, time traveling)
  • Array metadata
  • Array groups
  • Numerous APIs on top of the C++ library
  • Numerous integrations (Spark, Dask, MariaDB, GDAL, etc.)

You can use TileDB to store data in a variety of applications, such as Genomics, Geospatial, Finance and more. The power of TileDB stems from the fact that any data can be modeled efficiently as either a dense or a sparse multi-dimensional array, which is the format used internally by most data science tooling. By storing your data and metadata in TileDB arrays, you abstract all the data storage and management pains, while efficiently accessing the data with your favorite data science tool.


You can install the TileDB library as follows:

# Homebrew (macOS):
$ brew update
$ brew install tiledb-inc/stable/tiledb

# Or Conda (macOS, Linux, Windows):
$ conda install -c conda-forge tiledb

Alterantively, you can use the Docker image we provide:

$ docker pull tiledb/tiledb
$ docker run -it tiledb/tiledb

We include several examples. You can start with the following:


You can find the detailed TileDB documentation at https://docs.tiledb.com.

Format Specification

The TileDB data format is open-source and can be found [here](format_spec/FORMAT_SPEC.md).


The TileDB team maintains a variety of APIs built on top of the C++ library:


TileDB is also integrated with several popular databases and data science tools:
