indexed_entity_store 2.0.0-dev3

A fast, simple, and synchronous entity store for Flutter applications.

2.0.0

• Update method names
  • Most notably insert is now write to transmit the ambivalence between "insert" and "update"
  • get is now read to be symmetric to write (but instead of entities it takes keys, of course)
  • query now takes an optional where parameter, so instead of getAll() you can now just use query() to get the same result
  • delete now bundles multiple ways to identify entities to delete, offering a simpler API surface for the overall store
• Support foreign key (referencing) and unique constraints on indices
  • With referencing one can ensure that the index's value points to an entityt with the same primary key in another store
  • A unique index ensures that only one entity in the store uses the same value for that key

1.4.7

• Add contains functions for String index columns

1.4.6

• Re-enable foreign key constraint for every session
  • Clean up unused indices which were not automatically removed before (but will be going forward)

1.4.5

• try/catch with ROLLBACK in case a transaction fails, so as to not leave the database in a locked state
• Re-add explicit deletion of index, as REPLACE INTO was observed to not remove the entity's index on all platforms (and there is no clear documentation under what circumstances it would do or not do so)

1.4.4

• Add another example, showing how to build repositories with a Future<ValueListenable<T>> interface
• Fix index migration bug (introduced in 1.4.3), when a name is reused across index versions

1.4.3

• Add insertMany method to handle batch inserts/updates
  • This, combined with a new index, massively speeds up large inserts:
    • Inserting 1000 entities with 2 indices is now 40x faster than a simple loop using inserts individually
    • When updating 1000 existing entities with new values, the new implementation leads to an even greater 111x speed-up
  • This further proves that the synchronous database approach can handle even large local databases and operations. If you need to insert even larger amounts of data without dropping a frame, there is a solution for that as well.

1.4.2

• Add full example app
• Implement DisposableValueListenable for QueryResult

1.4.1

• Add deleteAll method

1.4.0

• Enhance subscriptions to not emit updates when the underlying database value has not changed
  • E.g. when an object is updated with the exact same storage values or a query ends up with the same result list no updates are emitted
• Fix unsubscribe for queries

1.3.0

• Add single/singleOnce for cases where one expects a single match, but does not have a primary key
• Add limit and orderBy to query/queryOnce
• Add orderBy to getAll/getAllOnce

1.2.2

• Fix index query building on Android / latest sqlite3_flutter_libs

1.2.1

• Fix DB init with the latest SQLite from sqlite3_flutter_libs on Android

1.2.0

• Typed indices: All queries not check the parameter types, such that one does not accidentally pass a String to an int index field for example.
  • These are checked at runtime, as the interface does not allow specifying the type signature per column
  • Additional the index-building specification has been changed, to be able to discern field which are nullable and those which must not be
• Add more query methods: less than (or equal) and greater than (or equal)

1.1.1

• Add deleteEntity in case the caller does not have access to the primary key used by the connector (e.g. if it's a combined one)

1.1.0

• Adds reactivity
  • Callers now get notified for every update to their queries
  • All queries are now reactive by default, so queries can be composed without missing any updates. This is highly useful unless the synchronizations happens on a higher application layer, in which case the *Once methods can be used.

1.0.0

• Initial release.
