Tantivy ADR

Author Marko Budiselic (github.com/gitbuda)

Status APPROVED

Date January 5, 2024

Problem

For some of Memgraph workloads, text search is a required feature. We don't want to build a new text search engine because that's not Memgraph's core value.

Criteria

  • easy integration with our C++ codebase
  • ability to operate in-memory and on-disk
  • sufficient features (regex, full-text search, fuzzy search, aggregations over text data)
  • production-ready

Decision

All known C++ libraries are not production-ready. Recent Rust libraries, in particular Tantivy, seem to provide much more features, it is production ready. The way how we'll integrate Tantivy into the current Memgraph codebase is via cxx. We select Tantivy.
