looseleaf

looseleaf

The looseleaf package implements an HTTP-accessible key/value database with ACID semantics and fine-grained role-based access control.

Features

• ACID semantics.
• Atomic reads and updates for arbitrary sets of keys. An unlimited number of keys can be read, updated, and/or deleted in a single operation that is atomic with respect to all other database operations.
• Fine-grained role-based access control.
• A trivial HTTP interface for easy access from shell scripts.
• A strictly defined JSON protocol with a full schema.
• Convenient endpoints for use with command-line tools such as curl.
• A small, easily auditable codebase with a heavy use of modularity for correctness.
• An extensive automated test suite with high coverage.
• A small footprint; the server is designed to run in tiny 16-32mb JVM heap configurations.
• Platform independence. No platform-dependent code is included in any form, and installations can largely be carried between platforms without changes. The database file format is also platform-independent.
• Security-conscious engineering. All requests require authentication, extensive validation is performed on all requests, and careful use is made of the Java type system to enforce invariants throughout the codebase.
• Fully instrumented with OpenTelemetry for reliable service monitoring.
• Configurable fault injection for testing monitoring.
• OSGi-ready
• JPMS-ready
• ISC license.
