Modern Paging at Scale: StoreX + Compose
summary
A paging system built on Store and Compose (molecule) that targets TikTok-scale heterogenous feeds, claiming UDF-first flow and item-level viewmodels called updating items to avoid full-source invalidation. It adds an operation pipeline for on-the-fly filtering, deduplication, sorting and grouping, supports local and remote mutations, uses Store + Guava caching, and exposes middleware, side‑effects, fetching and error strategies. Benchmarks show parity with AndroidX paging but fewer janky frames and far fewer recompositions.
