1//! Vectorized query execution engine.
2//!
3//! Grafeo uses vectorized processing - instead of one row at a time, we process
4//! batches of ~1024 rows. This unlocks SIMD and keeps the CPU busy.
5//!
6//! | Module | Purpose |
7//! | ------ | ------- |
8//! | [`chunk`] | Batched rows (DataChunk = multiple columns) |
9//! | [`vector`] | Single column of values |
10//! | [`factorized_vector`] | Factorized vectors for avoiding Cartesian products |
11//! | [`factorized_chunk`] | Multi-level factorized chunks |
12//! | [`selection`] | Bitmap for filtering without copying |
13//! | [`operators`] | Physical operators (scan, filter, join, etc.) |
14//! | [`pipeline`] | Push-based execution (data flows through operators) |
15//! | [`parallel`] | Morsel-driven parallelism |
16//! | [`spill`] | Disk spilling when memory is tight |
17//! | [`adaptive`] | Adaptive execution with runtime cardinality feedback |
18//!
19//! The execution model is push-based: sources push data through a pipeline of
20//! operators until it reaches a sink.
