This module provides an implementation of the [`HotKv`] trait using MDBX as +//! the underlying database. It includes functionality for opening and +//! managing the MDBX environment, handling read-only and read-write +//! transactions, and managing database tables. +//! +//!

This implementation uses the default MDBX table to store metadata about +//! each table, including whether it uses dual keys or fixed-size values.

Creating multiple tables +//! with the same name but different metadata in different transactions +//! may lead to inconsistencies. +//! - Tables created outside of this implementation (e.g., via external tools) +//! will not have their metadata cached, which may lead to inconsistencies if +//! the same table is later opened with different metadata. +//! +//!

Signet Storage Components +//! +//! High-level abstractions and implementations for storage backends used in +//! Signet. +//! +//! ## Design Overview +//! +//! We divide storage into two main categories: cold storage and hot storage. +//! The distinction is not access patterns, but whether the data is used in the +//! critical consensu s path (hot) or not (cold). Cold storage is used for +//! serving blocks and transactions over RPC, while hot storage is used for +//! fast access to frequently used data during block processing and consensus. +//! +//! The crate has two modules: +//! - [`cold`]: Cold storage abstractions and implementations. +//! - [`hot`]: Hot storage abstractions and implementations. +//! +//! ## Hot Storage +//! +//! Hot storage is modeled as a key-value store with predefined tables. The core +//! trait is [`HotKv`], which provides a factory for creating read and write +//! transactions. +//! +//! The primary traits for accessing hot storage are: +//! - [`HistoryRead`]: for read-only transactions. +//! - [`HistoryWrite`]: for read-write transactions. +//! +//! Other traits should generally only be used when implementing new backends. +//! +//! [`HotKv::revm_reader`] and [`HotKv::revm_writer`] create a transaction +//! wrapper that implements the [`revm`] crate's storage traits, allowing +//! seamless integration with the EVM execution engine. +//! +//! When the "mdbx" flag is enabled, we provide an MDBX-based implementation of +//! the hot storage traits. See the `hot_impls::mdbx` module for more details. +//! +//! ## Cold Storage +//! +//! Cold storage provides abstractions for storing and retrieving blocks, +//! transactions, and related data. +//! +//! Unlike hot storage, cold is intended to be accessed asynchronously. The core +//! trait is [`ColdStorage`], which defines methods for appending and reading +//! from the store. +//! +//! A [`ColdStorage`] implementation is typically run in a separate task using +//! the [`ColdStorageTask`]. The task processes requests sent via a channel, +//! allowing non-blocking access to cold storage operations. The +//! [`ColdStorageHandle`] provides an ergonomic API for sending requests to the +//! task. +//! +//! Like [`hot`], the majority of users will not need to interact with cold +//! storage directly. Instead, they will use the task and handle abstractions. +//! +//!
