Research direction
This issue requests a Presto connector for Vespa. First, study existing Presto connectors (e.g., for Elasticsearch) in the Presto codebase to understand the API and SPI. Then examine Vespa's HTTP REST API documentation and any existing integration patterns. Consider starting with a proof of concept that implements basic query pushdown and data retrieval. The issue has no recent maintainer input, so it's advisable to open a discussion in the issue to clarify scope and acceptance criteria.
