>Rust, Polars
Same, more specifically:
* Archived market data is in binary format (DBN and ethABI) and zero copy, derived data (features, signals, etc) is in Parquet for post-hoc analysis (Polars, DuckDB)
* Message passing between actors via SPSC channels over ring buffers (no callbacks), using codegen to generate message schemas and wiring between actors, as well as services within each actor, for consistency (including fan-in from multiple SPSC channels, with timestamp awareness for synchronization and backpressure)
* Actor boundaries have pluggable transports for switching to SHM, IPC or TPC if desired (codegen'd so config-driven, no manual code changes)
* Parallelization achieved by spawning N separate actors all consuming from the same feed (or more generically, any upstream event source), or purely synchronous with Rayon for quicker sweeps if applicable (eg populating a feature cache)
* Strategies/Features and Portfolio/Risk logic is composable and decoupled
