basho/riak_core

This system is a distributed cluster management framework that handles node coordination, ring topology, and data handoff. It provides optimized data structures for consistent hashing and version vector tracking, while offering a comprehensive configuration schema for cluster behavior. The system includes robust tooling for background resource management and extensive property-based testing to verify core reliability.

The \include\ directory received several new header files and updates to existing ones to support new internal capabilities. A new \riak\_core\_bg\_manager.hrl\ introduces type definitions and records for a background resource manager (locks and tokens) used to coordinate shared resources. The \riak\_core\_handoff.hrl\ is significantly expanded with new records for handoff statistics, types, and status tracking, enabling more granular visibility into handoff progress. Additionally, \riak\_core\_vnode.hrl\ introduces a new \riak\_coverage\_req\_v1\ record and updates the \riak\_core\_fold\_req\_v2\ record, while \riak\_core\_ring.hrl\ defines current and legacy ring version numbers. These changes collectively enhance the system's ability to manage background tasks, track handoff states, and handle coverage requests.

Added new Erlang modules chashbin and dvvset to the src directory. chashbin provides a binary representation of consistent hash rings, enabling efficient iteration and lookup of partition ownership. dvvset implements a compact Dotted Version Vector (DVV) container for managing concurrent value versions. These modules support the broader cluster metadata and ring management capabilities by providing optimized data structures for hash-based partitioning and version tracking.

A new \riak\_core.schema\ file has been added to the \priv\ directory, introducing a comprehensive set of configuration mappings for Riak Core. This schema defines settings for bucket properties (such as \n\_val\ and \ring\_size\), handoff controls (including \handoff.ip\, \handoff.port\, \handoff.ssl\ options, and inbound/outbound flags), and platform-specific directory paths. The schema includes validators to ensure ring sizes are powers of two and within acceptable bounds, and it exposes settings like \dtrace\ support and \transfer\_limit\ for data handoff concurrency.

The riak\_core.app file has been removed from the ebin directory. This change likely reflects a build system update where the .app file is now generated or managed differently, rather than being a static file in the output directory.

ebin · high confidence

The project now requires Erlang/OTP 22.0 or later, as indicated by the new minimum OTP version constraint in rebar.config. The build system has been updated to use rebar3, with the Makefile targets refactored to use the $(REBAR) variable. Additionally, the configuration enables warnings as errors, adds xref and dialyzer checks, and updates dependencies to use specific branches (e.g., poolboy, clique, eleveldb) rather than fixed versions or older repositories.

(repo-wide) · high confidence

Added new EQC property-based tests for core components; Expanded automated test coverage for core subsystems.
