Tradeoffs

The gateway adds a network hop and performs validation, routing, and result merging for Layer-specific requests. Wider scans and federated queries can increase upstream work and gateway memory use.

The local Compose database uses a persistent Docker volume. Back up that database according to your durability needs. Removing its volume erases the local rows.

Turbopuffer sharding and write timestamps add reserved indexed attributes. Store capabilities differ: check the matrix before relying on the same query shape across backends.
