Below are four diagrams illustrating on how data is served from static files to the provider. A glossary is also provided to explain the different (linked) components involved in these processes.

### Glossary
In descending order of abstraction hierarchy:

[`StaticFileProducer`](../../crates/static-file/src/static_file_producer.rs#L25): A `reth` [hook](../../crates/consensus/beacon/src/engine/hooks/static_file.rs) service that when triggered, **copies** finalized data from the database to the latest static file. Upon completion, it updates the internal index at `StaticFileProvider` with the new highest block and transaction on each specific segment.

Upon completion, it updates the internal index at `StaticFileProvider` with the new highest block and transaction on each specific segment.

[`StaticFileProvider`](../../crates/storage/provider/src/providers/static_file/manager.rs#L44) A provider similar to `DatabaseProvider`, **managing all existing static_file files** and selecting the optimal one (by range and segment type) to fulfill a request. **A single instance is shared across all components and should be instantiated only once within `ProviderFactory`**. An immutable reference is given every time `ProviderFactory` creates a new `DatabaseProvider`.

[`StaticFileJarProvider`](../../crates/storage/provider/src/providers/static_file/jar.rs#L42) A provider similar to `DatabaseProvider` that provides access to a **single static file segment data** one a specific block range.

[`StaticFileCursor`](../../crates/storage/db/src/static_file/cursor.rs#L11) An elevated abstraction of `NippyJarCursor` for simplified access. It associates the bitmasks with type decoding. For instance, `cursor.get_two::<TransactionMask<Tx, Signature>>(tx_number)` would yield `Tx` and `Signature`, eliminating the need to manage masks or invoke a decoder/decompressor.

[`StaticFileSegment`](../../crates/primitives/src/static_file/segment.rs#L10) Each static file only contains data of a specific segment, e.g., `Headers`, `Transactions`, or `Receipts`.

[`NippyJarCursor`](../../crates/storage/nippy-jar/src/cursor.rs#L12) Accessor of data in a `NippyJar` file. It enables queries either by row number (e.g., block number 1) or by a predefined key not part of the file (e.g., transaction hashes). **Currently, only queries by row number are being used.** If a file has multiple columns (e.g., `Header | HeaderTD | HeaderHash`), and one wishes to access only one of the column values, this can be accomplished by bitmasks. (e.g., for `HeaderTD`, the mask would be `0b010`).

[`NippyJar`](../../crates/storage/nippy-jar/src/lib.rs#92) An append-or-truncate-only file format. It supports multiple columns, compression (e.g., Zstd (with and without dictionaries), lz4, uncompressed) and inclusion filters (e.g., cuckoo filter: `is hash X part of this dataset`). StaticFiles are organized by block ranges. (e.g., `TransactionStaticFile_0_-_499_999.jar` contains a transaction per row for all transactions between block `0` and block `499_999`). For more check the struct documentation.
