cabol/shards

This system is a lightweight Erlang library that provides a sharded interface for managing multiple ETS (Erlang Term Storage) tables. It offers utilities for parallel execution and enumerable processing, including a parallel map function. The codebase is supported by comprehensive test suites that verify the correctness of read, write, and query operations against the underlying storage layer.

The repository was initialized with essential build and configuration files, including a Makefile for managing the Rebar3 build system, a rebar.config defining compiler options, plugins, and test profiles, and a rebar.lock file. Additional configuration files such as .codecov.yml, .gitignore, and .tool-versions were also added to support continuous integration, code coverage reporting, and environment consistency.

(repo-wide) · high confidence

The library has been updated to version 1.1.1. This release includes the addition of the \parallel\_timeout\ option, which allows users to specify the maximum timeout for parallel executions, and the implementation of the \shards\_enum\ module, which provides utilities for working with enumerables, including a \pmap\ function for parallel mapping.

src · high confidence

Added new Common Test suites (shards\_SUITE, shards\_enum\_SUITE, shards\_group\_SUITE, shards\_lib\_SUITE, shards\_meta\_SUITE, shards\_opts\_SUITE) covering basic operations, query operations, parallel map/reduce, group management, metadata, and option parsing. Additionally, a new property-based state machine test (prop\_shards\_statem.erl) was introduced to verify the correctness of read/write commands against the underlying ETS tables, ensuring that the shards layer behaves identically to native ETS for a wide range of operations including insert, lookup, delete, and update.
