basho/riak-erlang-client

This system is an Erlang client library for interacting with the Riak distributed database. It provides a modernized build infrastructure and comprehensive support for Riak's eventually-consistent data types, including counters, flags, registers, sets, hyperloglogs, and maps. The library also facilitates standard database operations such as secondary indexing, search, and MapReduce queries, all backed by extensive unit and integration tests.

The \riakc.hrl\ header file is introduced, defining Erlang types and macros for the Riak protocol buffer client. This includes type specifications for client options, bucket and key identifiers, MapReduce query terms, and secondary index result records. It also defines constants for timeouts and connection parameters, enabling the client to support features like secondary indexes, search, and MapReduce with proper type checking.

include · high confidence

The client library now supports Riak's eventually-consistent data types, including counters, flags, registers, sets, generalised sets, hyperloglogs, and maps. These new modules (riakc\_counter, riakc\_flag, riakc\_register, riakc\_set, riakc\_gset, riakc\_hll, and riakc\_map) implement a common datatype behaviour, allowing users to perform local updates that are later applied to the server. The changes also include the addition of the riakc.app.src file to define the application structure and dependencies.

src · high confidence

The riakc application file (ebin/riakc.app) has been removed from the project. This change affects the packaging and structure of the Riak client library, potentially impacting how the application is loaded or referenced by the Erlang runtime.

ebin · high confidence

The visual presentation of the generated documentation (edoc) has been updated with new CSS rules. This includes baseline typography settings (font sizes, line heights, margins) for headings and paragraphs, specific styling for code blocks and preformatted text, and custom formatting for headers, lists, and function specifications to improve readability and visual hierarchy.

priv · high confidence

The client library now requires Erlang/OTP 20 or later, as reflected in the new \require\_otp\_vsn\ constraint in \rebar.config\. The build system has been modernized to use Rebar3, with the \Makefile\ delegating to \./rebar3\ for all build targets. Additionally, the \rebar.config\ file has been expanded to include EUnit verbosity, stricter compiler warnings, platform-specific defines for OTP 19 and 20 deprecations, and Xref checks for unused or undefined functions.

(repo-wide) · high confidence

Added new test suites for the Erlang client, including protocol buffer socket connection handling (auto-reconnect, linger options, and disconnected states), timeseries (TS) operations, and utility functions. The tests verify connection stability, client ID management, server version retrieval, and proper error handling for invalid operations like adding to an HLL map.
