How Upstash Redis Search Works?

Upstash Redis Search enhances Redis by integrating full-text search capabilities, using the open-source Tantivy library written in Rust as its search core. This integration allows for strong query operators and aggregations, addressing the limitations of Redis's traditional data querying methods. When a Redis command is executed, relevant data is indexed, stored, and queued on disk, ensuring durability, with the indexing process continuing asynchronously. Tantivy's design, splitting indexes into immutable segments stored as keys in a key-value database, enables global replication and efficient querying across regions. The integration is achieved by bridging Go and Rust through cgo, allowing the system to handle language boundaries effectively. The design ensures that documents are indexed efficiently without spawning excessive background threads, which is crucial for scalability in a multitenant database environment. The goal is to make the indexed data visible to search queries, with ongoing improvements aimed at enhancing performance and adding features like semantic search.
