Exporting a large collection (~4.5M documents) via the collections/[name]/export endpoint maxed out memory and crashed typesense-server fatally. The v0.24.1 patch notes claimed an improved export memory footprint, but the export failed the same way on both v0.24.0 and v0.24.1. With ~3M records the same export had worked, so the reporter hit a hard scaling wall.

The export memory blowup was comprehensively fixed in Typesense 0.25.0. Upgrade to 0.25.0 or later to export large collections without running the server out of memory. Source: https://github.com/typesense/typesense/issues/1067
