TileDB Embedded v2.3

Pushdown of attribute filtering

TileDB has always supported NumPy-like slicing across multiple dimensions. These dimensions are defined in advance when creating TileDB arrays. Now, users have the option to further refine results at query-time by pushing down attribute filtering to the storage engine. Filter by any number of attribute values contained within the array.

S3 server-side encryption

This release adds a new configuration parameter to specify the server-side encryption algorithm to use when working with TileDB arrays on Amazon S3. Valid options are aes256 (Amazon S3-managed encryption keys) and kms (AWS Key Management Service). In a related update, this release also includes AWS IAM AssumeRole support with automatic token refresh.

More options for time

NumPy datetime data types have long been supported as dimensions in sparse TileDB arrays. This release adds support for time data types (without associated dates) as both dimensions and attributes.

New Hilbert layout

This release adds a new Hilbert layout for efficient space-filling-curve ordering of cells. It also fixes some previous issues with partitioning.

Zero-copy import/export via Arrow

The TileDB adapter for Apache Arrow now supports zero-copy import/export for fast data exchange and efficient use of memory.

Nullable attributes

Working with missing data is now more efficient in TileDB and better aligns with modern dataframe conventions. Both fixed and variable-length attributes now support nullables. By default, fill values for nullable attributes will be null.

Updated cloud object storage support

This release adds TileDB support for read-ahead caching on cloud-storage backends and upgrades cloud provider SDKs to their latest versions within TileDB.

Configurable concurrency

Version 2.1 adds options for configuring concurrency levels and provides appropriate defaults.

A scalable variant store

We are releasing an open-source genomics customization called TileDB-VCF, which allows you to store arbitrarily large gVCF datasets as sparse 2D arrays in TileDB. With TileDB-VCF, you can solve the N+1 problem, achieving linear storage scalability, regardless your dataset size and number of updates.

40% space savings and scalability

TileDB-VCF reduces your collection of single-sample BCF files by 40%, leads to fast and scalable analysis on the cloud, and allows you to take advantage of the Data Science ecosystem via TileDB’s numerous integrations.

Embedded SQL

Pluggable storage engine

We added TileDB as a pluggable storage engine to MariaDB. You are now able to run fast SQL queries via your MariaDB server on TileDB arrays, stored either on premises or on the cloud (e.g., AWS S3).

TileDB Geospatial

Learn more

TileDB is integrated with PDAL, GDAL, and Rasterio, providing you a way to store your geospatial data in a single, cloud-optimized format.

TileDB Core v1.7

Learn more
Array metadata support

We added support for key-value array metadata that you can attach to any array.

Overhauling KV store

We removed KV objects that used to implement key-value functionality. We will soon introduce support for string dimensions, which will realize a full-fledged key-value store via TileDB arrays, allowing multi-dimensional and prefix-based string search.
