Implements tcp_conversations, a DataFusion table function that transforms raw pcap/pcapng packets into aggregate TCP connection flows (5-tuple keyed with byte/packet counts and timing). The packet-to-flow aggregation is self-contained domain logic — portable to any DataFusion-based network monitoring, security, or performance tooling.

Provides capture/capture_wide live packet-capture table functions, bridging blocking libpcap C calls into an async DataFusion source via a background thread and channel. Planning deliberately avoids opening the network device during EXPLAIN. This native-to-async bridge pattern is reusable for integrating any blocking C library with DataFusion streams.

A DedicatedExecutor (InfluxDB-inspired) that offloads CPU-bound query work to a dedicated tokio runtime while retaining the caller's IO runtime, preventing query execution from blocking server I/O. Self-contained concurrency primitive, directly reusable in any async service embedding DataFusion.

ExecutionPlanVisitor implementations that walk DataFusion physical plans to collect fine-grained IO and compute statistics (bytes read, rows scanned, per-operator timing). A portable visitor-based observability pattern for any project needing query-level metrics over DataFusion execution plans.

Exposes Parquet bloom-filter metadata as a queryable table, decoding low-level parquet crate structures (filter type, algorithm, hash function, bitset) into Arrow batches via the standard UDTF pattern. The decoding logic is isolated within a dedicated crate and reusable for any Parquet inspection or data-profiling tool.

Bridges WASM linear memory and Arrow IPC: the guest allocates memory via an exported alloc function, and the host constructs Arrow IPC buffers (record batches) directly from that memory region. A non-obvious FFI design for running cross-language UDFs, extractable as a template for WASM-based extension systems in Arrow-native projects.
