Overview ¶
Package encoding holds the L2 codec layers (DESIGN.md §3, §14 M0):
- [bitstream]: MSB-first bit stream reader/writer (the foundation)
- encoding/chunk: value-column codecs (DoD, Gorilla, T64, dictionary, scaled-decimal)
- encoding/compress: zstd/lz4 block wrappers and codec chains

Types ¶
type Profile ¶
type Profile struct {
}
Profile is the default codec-chain profile per column kind (DESIGN.md §6). It is consumed by [storage.Options] and applied when flushing a part. Zero values mean "use the built-in default chain for that column kind".
This is a scaffold stub; the concrete chain type is filled in at M0 as the codecs land. It is a placeholder now so the [storage.Options] shape is stable.

Package compress wraps zstd/lz4 block compression and defines the composable codec-chain type (preprocessor → general compressor) used to reach 0.4–0.8 bytes/point (DESIGN.md §3.3, §14 M0).
