💡 Overview
speedtables is an open-source project written in Tcl: Speed tables is a high-performance memory-resident database. The speed table compiler reads a table definition and generates a set of C access routines to create, manipulate and search tables containing millions of rows. Currently oriented towards Tcl.
Engineered for speed, consistency, and developer ease, it solves common hurdles in caching, nosql-data-storage, shared-memory. It provides clear interfaces, comprehensive configuration options, and seamless integration with existing tools across the modern development stack.
⚡ Key Features
Optimized execution pipeline written in Tcl for predictable speed.
Zero-friction configuration with comprehensive sensible defaults out of the box.
Cross-platform runtime support across Linux, macOS, and Windows environments.
Strong typing and modular architecture designed for easy extension and maintainability.
Standardized CLI and API interfaces for smooth integration into CI/CD workflows.
Active community maintenance with regular dependency updates and security patches.

🧠 How It Works
speedtables coordinates its core functionality through a modular Tcl pipeline. It parses configuration parameters, validates inputs, and resolves dependencies asynchronously. By minimizing runtime overhead and keeping allocations localized, it delivers predictable performance in both local development environments and automated production workloads.
🎯 Production Use Cases
High-Throughput Storage
Persist and retrieve structured data records with minimal latency and high concurrency.
In-Memory Caching
Accelerate application response times by caching frequently queried database entities.
Analytical Queries
Run aggregate metrics and point lookups across large sets of records.
Distributed Replication
Synchronize state across multiple cluster nodes with strong consistency guarantees.
