One quick sketch of offline-first (there are many other ways): imagine a database like DataScript (already OSS and built in Clojure), move key components like the query engine into Electric Clojure, now the "DAG slice" can cut right through the query engine and it's internal data structures, such that the indexes are partially on the client, and the final stages of query filtering are on the client. A network-transparent database! The bulk of the work, and sensitive data, stays on the server; but the last mile user data querying happens on the client. Electric can transparently move portions of the underlying database indexes to the client for local offline query. 0 LOC cost to userland! No loss of relational query when offline! No performance cost of putting the entire query engine in the browser (a low compute environment)!
