Wildcard searches (LIKE and ILIKE) are common in PostgreSQL applications, but they often become a major performance bottleneck. Traditional B-tree indexes only optimize prefix searches, while pg_trgm can produce false positives that require expensive heap rechecks.
This session introduces Biscuit, an open source PostgreSQL extension that uses a new bitmap-based indexing approach to accelerate wildcard pattern matching. Learn how Biscuit integrates with the PostgreSQL query planner, avoids unnecessary heap rechecks, and delivers faster, more predictable query performance for text-heavy workloads.
We’ll explore the indexing algorithm, benchmark results against B-tree and pg_trgm, practical use cases, and the trade-offs of building a custom PostgreSQL index access method. Whether you’re a PostgreSQL DBA, database developer, or systems engineer, this talk offers valuable insights into query optimization and PostgreSQL internals.
