@concile/query-engine

The read side of the Concile engine: index range scans, filters, ordering, and cursor pagination over the document log.

This package turns a query built in application code into an index range scan, applies post-filters and ordering, and returns results with stable cursors for pagination. While doing so it records exactly which index ranges were read — the read set — which the sync tier later intersects with committed write sets to decide which subscriptions to re-run. It also computes the index updates a write implies, keeping indexes consistent as documents change.

It pairs with the transactor's write side to close the reactive loop: precise read sets from here, precise write sets from there, and an intersection between them is what triggers a live update.

This is an internal package of the Concile engine. Most applications should install concile instead.
