cindel 0.2.13

Ultra-fast, lightweight NoSQL local database for Flutter and Dart apps, powered by a compact Rust native core.

Changelog

0.2.13

• Added CindelPropertyQuery aggregate helpers for count, min, max, sum, and average.
• MDBX can execute supported property aggregates over native binary documents without hydrating full Dart objects.
• Kept SQLite behavior compatible through fallback aggregate evaluation.
• Added FFI bindings for native aggregate queries and bumped the native ABI to 9.
• Declared Linux in pub.dev platform metadata now that Linux prebuilt generation is part of release validation.
• Completed release hardening for the optimized MDBX default storage path.

0.2.12

• Promoted the faster MDBX v2 table layout into the real MDBX backend path.
• MDBX now stores documents in per-collection tables and indexes in per-index duplicate-sorted tables while preserving the existing public Dart API.
• Kept binary documents, explicit transactions, unique/composite/multi-entry indexes, and optimized auto-increment counters on the converged backend.
• Added watcher change sets for local writes, including changed document ids and written documents when Dart has them available.
• Document and query watchers can skip safe local reads when a write does not affect the watched document or visible query result.
• Left the Rust-only mdbx-v2-spike path as a temporary benchmark fixture behind the explicit --backend all-with-spike option.

0.2.11

• Reduced MDBX allocations in id scans, range/equality query scans, collection stats, and multi-document reads.
• Reused MDBX document-key buffers for get_many paths outside active write transactions.
• Kept the existing safe MDBX cursor API; lower-level cursor work remains deferred until benchmarks prove it is needed.

0.2.10

• Optimized MDBX auto-increment id allocation with shared in-memory counters initialized from document primary keys.
• MDBX no longer writes persisted counter rows for the normal generated auto-increment insert path.
• Added native benchmark operations for id allocation and auto-increment indexed writes.
• Fixed explicit SQLite backend opening so it routes through the native backend selector instead of the default MDBX open symbol.

0.2.9

• Added collection-level composite index schema metadata and generated equality query helpers.
• Added multi-entry primitive list indexes for generated membership queries.
• Added native composite index key encoding and SQLite compatibility handling.
• Updated the annotations dependency to 0.2.1 and the generator dependency to 0.2.3.

0.2.8

• Added a first native query planner path for MDBX binary-document queries.
• Count and simple windowed list queries now use native candidate ids before document hydration when sort/distinct processing is not required.
• Added native single-field projection over binary document bytes.
• Added FFI bindings for native projection queries and bumped the native ABI to 8.

0.2.7

• Added native MDBX filtering for generated Cindel filter predicates over binary document bytes.
• Routed supported generated filter() and where().filter() queries through native filtering on MDBX, with the existing Dart filter path retained for SQLite and custom predicates.
• Added FFI bindings for native filter queries and bumped the native ABI to 7.

0.2.6

• Added generated binary document callbacks to collection schemas.
• Added MDBX typed collection write and read paths that use Cindel binary document bytes instead of JSON map decoding.
• Added FFI bindings for raw stored document reads and bumped the native ABI to 6.
• Kept SQLite available on the existing JSON document path.
• Updated the development generator dependency constraint to the 0.2.2 release line.

0.2.5

• Switched MDBX schema-backed document storage to Cindel's native binary document format.
• MDBX now derives index entries from binary document bytes for generated schema collections.
• Made schema-backed MDBX writes strict: unknown fields are rejected instead of falling back to JSON.
• Removed the public migration callback and dry-run APIs while Cindel remains pre-1.0 and the optimized storage format is still settling.
• Made MDBX part of the default native Cargo build while keeping SQLite compiled as an explicit secondary backend.
• Moved the native benchmark and experimental MDBX layout prototype behind the benchmarks Cargo feature so production builds stay smaller.
• Updated the native MDBX default path so the Rust engine opens MDBX by default when the native library is compiled with MDBX support.
• Bumped the native ABI to 5 for the migration API cleanup.

0.2.4

• Added internal storage metadata for layout and document format versions.
• Added native storage verification helpers for layout, document-format, and index metadata.
• Kept the public Dart API, production storage behavior, and native binary symbols unchanged.

0.2.3

• Added an internal native binary document format prototype.
• Documented the planned versioned object layout for future generated serializers.
• Added native tests for round-tripping supported field shapes without JSON and reading one field by offset without full document decoding.
• Kept the public Dart API, production storage layout, and native binary symbols unchanged.

0.2.2

• Added an internal MDBX layout prototype for native performance benchmarks.
• Added a benchmark backend that compares SQLite, the current MDBX layout, and the layout prototype with the same workload.
• Kept the public Dart API, production storage layout, and native binary symbols unchanged.

0.2.1

• Added an internal MDBX index abstraction boundary for key creation, unique checks, index replacement, deletion, collection clearing, and index stats.
• Kept the existing MDBX storage layout and public Dart API unchanged.
• Updated the development generator dependency constraint to the 0.2.1 release line.

0.2.0

• Prepared the Cindel API package for the coordinated 0.2.0 release line.
• Updated hosted Cindel package constraints to ^0.2.0.
• Refreshed package documentation for MDBX as the default backend, SQLite as an explicit fallback, and the Android/Windows prebuilt binary scope.

0.1.18

• Made MDBX the default storage backend for new Cindel databases.
• Kept SQLite available through backend: CindelStorageBackend.sqlite.
• Updated package documentation for the default backend switch.

0.1.17

• Prepared the first pub.dev development preview.
• Switched Cindel package dependencies from local paths to hosted development preview constraints.
• Declared Android and Windows as the currently available prebuilt platforms.
• Added optional libmdbx dependency and Windows build probe behind the native mdbx Cargo feature.
• Documented MDBX-01 build feasibility and LLVM/libclang requirements.
• Updated Cindel package dependency constraints for the next development preview.
• Removed dates from changelog headings so pub.dev renders version labels cleanly.
• Added the internal Rust backend selection boundary while keeping SQLite as the FFI default backend.
• Fixed an analyzer lint reported by pub.dev for an unnecessary await.
• Added a package example page for pub.dev.
• Added a library-level documentation comment for dartdoc/pub.dev analysis.
• Added the MDBX key encoding spike for document, index, unique index, and range-bound keys without changing the default SQLite backend.
• Added the feature-gated minimal MdbxStorage prototype and benchmark backend selection for SQLite, MDBX, or both.
• Expanded the native benchmark to cover open, schema registration, indexed writes, reads, indexed queries, batch writes, and deletes for the MDBX first adoption decision.
• Added shared Rust StorageEngine contract tests for SQLite and MDBX.
• Brought MDBX storage parity up to the non-explicit-transaction contract, including schema versions, compatible migrations, unique index enforcement, batch rollback, ids, revisions, and indexed reads/writes.
• Added MDBX explicit transaction integration through an internal write log that commits staged writes inside one MDBX transaction without storing self-referential transaction handles.
• Added shared Rust transaction contract tests for SQLite and MDBX covering commit, rollback, read transaction write rejection, nested transaction rejection, and id allocation rollback.
• Added the public CindelStorageBackend option and FFI backend selector so callers can explicitly choose SQLite or MDBX while SQLite remains the default backend.
• Added backend-parameterized Dart tests so the full Cindel package suite can run against SQLite or MDBX.
• Added MDBX read-your-writes parity for staged write transactions and shared same-directory MDBX environments across multiple Dart database handles.
• Updated package installation snippets for the MDBX-enabled Android and Windows prebuilt binaries.
