# You Should Reinvent The Wheel

Key Takeaways

The Case for Reinventing the Wheel

Conventional wisdom says don't reinvent the wheel. Laverdure argues the opposite: reinvention is how technology evolves and how developers grow.

• Most of what we do as developers boils down to storing and retrieving text from a database — even LLMs are just doing this with synthesized text
• Progress happens through repetition, refinement, and reinvention
• Great tools in the Laravel ecosystem (by Taylor, Adam Wathan, Caleb Porzio, Nuno Maduro) all reinvented existing solutions
• Chick-fil-A's cookie analogy: something familiar done really, really well can beat "revolutionary"

From Self-Doubt to Self-Development

The missing step between "I don't think I can do it" and "I can do it" is "I'm learning how to do it."

• The jazz parallel: you don't invent your own style first — you transcribe solos from Miles Davis, Cannonball Adderley, Wes Montgomery, internalize their phrasing, then play in your own way
• "Get in the shed" — seclude yourself and master the technique
• Ego says discover it alone; reality is mimicking others fills your bag so you can eventually improvise

Building Litebase: A Distributed SQLite Database

The talk pivots into the story of Litebase, an open source distributed database built on SQLite, backed by distributed file systems and object storage.

The problem: SQLite expects the database file on local disk. Making it work reliably across multiple app servers and queue workers is non-trivial.

First attempt (2019, Laravel Vapor + AWS Lambda + EFS):

• Reading from the database over EFS was easy; writing was complex
• SQLite coordinates access via file locking — painfully slow over the network
• Network file systems don't support memory-mapped files, which SQLite relies on for concurrent read/write coordination

Litebase Server architecture:

• Embed SQLite on local disk in a single Go binary
• HTTP communication layer with a connection manager
• Virtual File System hook into SQLite to manage all IO in heap memory (works around the mmap gap on NFS)
• Adds authentication, authorization, clustering, primary election via lease mechanism

The corruption incident:

• By default each SQLite connection has an isolated page cache — broken cache invalidation causes corruption on replicas and primary
• Single-instance SQLite offers serializable isolation; distributed replicas cannot guarantee it
• Reading a page out of order, writing to the wrong place, or returning wrong database size → corruption

Litebase DFS: The Structured Log

To fix consistency, Laverdure rewrote storage from scratch as a "structured log" — inspired by log-structured merge trees.

- Versioned Write-Ahead Logs — instead of one journal, multiple immutable timestamped WALs created on checkpoint, reducing contention - Page logs — indexed groups of database changes with immutable timestamps, holding data flushed from WALs - Dynamic Data Ranges — the foundational layer; subsets of the database split across many files so a single logical database can scatter across object storage and scale to terabytes - Result: a multi-version log-structured merge tree allowing transactions on a consistent snapshot at a point relative to their start - Features unlocked: intelligent data tiering, non-blocking backups, point-in-time restore, database branching, compression, encryption

Laravel Integration and LQTP

Litebase Server exposes a JSON API with parameterized queries.

- Custom Laravel database connection class reusing the existing SQLite processor and grammar - Custom PDO class that sends queries over HTTP instead of calling the local SQLite library - Just add driver config — drop-in

Benchmark (100 migrations, ~200 queries):

LQTP — Litebase Query Transfer Protocol:

• Custom binary protocol on top of HTTP, ditching per-request headers and JSON marshalling overhead
• Asynchronous bidirectional streaming, interactive transactions, data framing, implicit batching
• PHP client uses stream_socket_client + PHP fibers for async control flow — no third-party libs, no FFI, no extensions
• 33% efficiency gain over JSON, closing the gap on local SQLite

Notable Quotes

Every sunrise brings new possibilities. Repetition, refinement, reinvention. It's not a waste of time. It's how we evolve technology.

Nadia Boulanger, Quincy Jones' French music teacher:

Quincy, there are only 12 notes until God gives us 13. I want you to know what everybody did with those 12.

How I'll Apply This

The core lesson isn't "always reinvent" — it's that the learning deposited from the attempt is never wasted, even if the project never ships. Two things I'm taking away:

1. When considering whether to build vs. adopt, weigh the knowledge deposit alongside the shipped-feature outcome. "Fill your bag" is a legitimate reason to build something that already exists.
2. The self-doubt → self-development → confidence progression is a debugging tool for stalled projects. If I'm stuck at "I don't think I can," the fix is transcription: read the docs, read other people's code, mimic before improvising.

Litebase itself is worth watching — an SQLite-based distributed database with a custom binary protocol is directly relevant to any project weighing SQLite for production at scale (litebase.com).
