Quilt is a data registry

Quilt provides versioned, reusable building blocks for analysis in the form of data packages. A data package may contain data of any type or size. In spirit, Quilt does for data what package managers and Docker registries do for code: provide a centralized, collaborative store of record.


  • Reproducibility - Imagine source code without versions. Ouch. Why live with un-versioned data? Versioned data makes analysis reproducible by creating unambiguous references to potentially complex data dependencies.
  • Collaboration and transparency - Data likes to be shared. Quilt offers a centralized data warehouse for finding and sharing data sets.
  • Auditing - the data registry tracks all reads and writes so that admins know when data are accessed or changed
  • Less data prep - Quilt abstracts away network, storage, and file format so that users can focus on what they wish to do with the data.
  • Deduplication - Data fragments are hashed with SHA256. Duplicate data fragments are written to disk once globally per user. As a result, large, repeated data fragments consume less disk and network bandwidth.
  • Faster analysis - Serialized data loads 5 to 20 times faster than files. Moreover, specialized storage formats like Apache Parquet minimize I/O bottlenecks so that tools like Presto DB and Hive run faster.
