    Cap'n Proto

    Cap'n Proto

    Serialization/RPC system - core tools and C++ library

    Cap’n Proto is a high-performance serialization and RPC system with core tools and a C++ library. It is designed as a binary data interchange format that can replace JSON, Protocol Buffers, or similar schema-based formats in performance-sensitive systems. The project uses schemas to define structured data and interfaces, then generates code for working with those messages efficiently. Its RPC model is capability-based, which makes it suitable for distributed systems that need object-style communication across processes or machines. The repository contains the main compiler, C++ runtime, KJ library components, tests, style guidance, release tooling, and development branches. ...

    Grafbase

    Grafbase

    The Grafbase GraphQL Federation Gateway

    ...The project provides a Rust-based gateway that acts as the central layer for composing and managing distributed APIs, particularly in microservice architectures where data may come from many independent systems. By supporting GraphQL federation standards, the platform enables teams to combine multiple subgraphs or services into a unified schema that clients can query as a single endpoint. Grafbase is designed for large-scale production environments, emphasizing high throughput, low latency, and efficient resource usage through its Rust implementation. The system also includes tools for schema governance, API lifecycle management, and collaboration workflows, helping engineering teams safely evolve complex APIs over time.

    GraphQL Batch

    GraphQL Batch

    A query batching executor for the graphql gem

    ...Define a custom loader, which is initialized with arguments that are used for grouping and a perform method for performing the batch load. Use GraphQL::Batch as a plugin in your schema after specifying the mutation so that GraphQL::Batch can extend the mutation fields to clear the cache after they are resolved. The loader class can be used from the resolver for a graphql field by calling .for with the grouping arguments to get a loader instance, then call .load on that instance with the key to load. Although this library doesn't have a dependency on active record, the examples directory has record and association loaders for active record which handles edge cases like type-casting ids. ...

    Gradle JOOQ Plugin

    Gradle JOOQ Plugin

    Gradle plugin that integrates jOOQ

    The Gradle jOOQ Plugin automates the code generation process for jOOQ, a popular database access library for Java that creates type-safe query DSLs from database schemas. It wires jOOQ’s code generator into the Gradle build lifecycle, so whenever the schema changes, developers can regenerate matching Java classes directly through a Gradle task. The plugin handles dependencies, classpaths, and configuration options for connecting to different databases. It supports customization of generator options, such as output directories, package names, and which tables or schemas to include. By automating schema-to-code generation, the plugin keeps the application’s data model and database in sync. ...

    Data Contract CLI

    Data Contract CLI

    Enforce Data Contracts

    ...It uses YAML-based contract files to define the structure, meaning, quality rules, service levels, and connection details for a data product. The tool can connect to real data sources and check whether the actual dataset matches the schema, constraints, and quality expectations described in the contract. It supports both the Data Contract Specification and the Open Data Contract Standard, making it useful for teams standardizing data governance across different platforms. It can run locally, inside CI/CD pipelines, through Docker, or directly from Python code. Overall, it helps data producers and consumers treat data products more like APIs, with explicit expectations, automated checks, and clearer accountability.

Slate's core logic assumes very little about the schema of the data you'll be editing, which means that there are no assumptions baked into the library that'll trip you up when you need to go beyond the most basic use cases. The document model used for Slate is a nested, recursive tree, just like the DOM itself. This means that creating complex components like tables or nested block quotes are possible for advanced use cases. ...
