Change Log

[1.0.0-beta.19]

Changed

  • Require WTI 0.0.12 and the backend/reclamation releases validated with beta.19 so an existing lockfile cannot retain an incompatible pre-fix version.
  • Require Arctic 0.1.9, including normalized validated-key prefix scans.

Fixed

  • Generated S3 engines now use the table's selected primary-index persistence adapter. Loaded default-Arctic tables can update, insert, delete, flush, and reopen without feeding logical Arctic events into the structural WTI disk format.

[1.0.0-beta.18]

Added

  • Selectable worktables_index, arctic, and congee backends for generated primary and supported secondary indexes, including persisted topology load.
  • Async and batched insert/delete paths, with bulk-mutation signaling used by reactive vacuum scheduling.
  • MemStat for generated persisted/read-only tables and Arc-owned unload_gracefully for generation swaps.
  • Strict persisted-state validation, schema metadata, recovery loading, and Arctic string/non-unique index support.

Changed

  • WorkTable row/page reclamation uses the local ps-reclaim domain regardless of the selected index backend. Arctic and Congee also select their local ps-reclaim SMR implementations; WorkTablesIndex retains its structural skip-list reclamation internally.
  • Readers now synchronize on the exact physical cell. Unrelated rows cannot block because of a hashed lock collision.
  • Vacuum discovers move candidates from a transient primary-index snapshot and keeps only one live-cell counter per page, removing the previous four-byte per-row directory.
  • Vacuum waits for three quiet observations after mutation activity and yields throughout a bulk mutation instead of competing with foreground work.
  • The archived wrapper retains the beta.17 inner-row position so legacy stores without bundled schema metadata remain readable.

Fixed

  • Torn reads and premature physical-link reuse during concurrent update, delete, and vacuum activity.
  • In-place replacement synchronizes through the runtime side-table cell lock; the beta.17 archived row bytes remain unchanged.
  • Whole-map Arctic destruction uses an unordered physical drain instead of repeatedly searching for the next logical key.
  • Persisted primary/secondary index reconstruction and validation failures that could otherwise expose missing, duplicate, or mismatched rows.

[0.4.1]

Added

  • add ability to choose index type in worktable! declaration.
  • added index_set and tree_index features to use index type as default in declaration.

BC Breaks

  • .wt files which are generated now have names as snake-case of table's name.
  • new function now has only DatabaseManager as argument.

Fixed

  • new function generated if persist: true now is public.
  • Bugs with insets and deletes after table load from file.

[0.4.0]

Added

  • SelectQueryBuilder object that is used to customize select_all query. It has limit and order_by methods that can be used to limit returned row's count. order_by has not full functionality and is only available for indexed columns and only Oreder::Asc.
  • SelectResult object with is partially same to SelectQueryBuilder. It allows to limit/order returned rows. Both Oreder::Asc and Oreder::Desc are available. No issues with not indexed columns.
  • added offset for SelectQueryBuilder and SelectResult.
  • added optional column attribute instead of explicit Option type declaration.
  • support for enums in queries
  • Added generation of Space object that represents file that stores table's data.
  • Added DatbaseManager object that is used to control multiple tables.
  • Added methods for Worktables to use data in files. persist is used to save data to file. load_from_file is used to load table from file.

BC Breaks

  • select_all now returns SelectQueryBuilder instead of Vec<Row>. To have same functionality old select_all users must call execute on returned builder.
  • select_by_{} now returns SelectResult instead of Vec<Row>. To have same functionality old select_all users must call execute on returned builder.

[0.3.10]

BC Breaks

  • Users don't need to define <{ TestRow::ROW_SIZE }> for insert, update and upsert.

Added

  • Support for Option types in columns.
  • Support of delete queries.

Fixed

  • Clippy errors in macro declaration about unused Result's.
