Q: How does Spandex perform scroll queries for large datasets?

Spandex offers scroll-chan that returns a core.async channel of result pages, enabling efficient streaming of large datasets with interruptible processing, as demonstrated in the README with loop and async operations.

Q: Is Spandex compatible with the latest Elasticsearch versions?

Yes, Spandex leverages Elasticsearch's REST client which is designed for compatibility with any Elasticsearch version, avoiding the pitfalls of the legacy transport client and ensuring future-proofing.

Question 1

How do I set up Spandex with HTTPS and SSH tunneling for AWS Elasticsearch?

Question 2

What's the difference between Spandex and clojure-elasticsearch?

Accepted Answer

Spandex wraps Elasticsearch's modern REST client for better performance and version compatibility, while clojure-elasticsearch often uses the legacy transport client; Spandex is more minimal and closer to the native API, whereas others might add more abstraction.
