Datastore 2.x releases

This page presents the release notes for all Datastore 2.x.x releases, listed in reverse chronological order.

2.8.0 release notes

Released: August 23, 2021

Updates:

  • Simulator and production Datastore can now define data segments.

Changes:

  • Security improvements

2.7.0 release notes

Released: July 12, 2021

Updates:

  • Pagination requests sent as direct HTTP requests to your data service’s API now encode special URL characters (according to RFC 3986 URI standards) within pagination links when the property page[v]=2 is submitted as part of the request’s query string.

Changes:

  • The simulator now returns an x-datastore-debug-error response header when it cannot find the blueprint.

  • Pagination links on collection aliases now return the collection alias path for the next and previous pages.

    Collection aliases are alternative collection paths (defined in the blueprint’s API specification file) that provide access to a common set of documents within a collection. This feature allows this common set of documents to be accessed through both its primary collection path and their alternative collection paths (and hence, 'collection aliases') in HTTP requests.

    Collection aliases allow custom access control (ACL) rules to be implemented across each one, thereby allowing a common set of documents to be accessible through their own ACL rules, governed by the ACLs defined within each collection alias.

  • You can now use properties of documents across a collection (and their collection aliases) to sort, filter, or aggregate their documents within the collection and its collection aliases. You can do this without having to specify properties in the blueprint through the collection or alias path.

Released: June 2, 2021

Updates:

  • The simulator now returns an x-datastore-upgrade response header when an upgrade is available.

Changes:

    • Returns a 400 response header on an invalid filter and invalid pagination queries.

    • Now support filtering by an empty string.

  • An error is thrown when blueprint property IDs with a space in their name are detected.

  • The validation of blueprints' collection aliases has been improved.

  • Additional security improvements have been implemented.

2.5.0 release notes

Released: March 22, 2021

Updates:

  • Security scanning and reporting have been improved.

2.4.0 release notes

JS SDK Array filtering examples

Student document course array contains ALL given course(s):

datastore.collection('students')
.where('courses', 'contains', 'course-a').get();

datastore.collection('students')
.where('courses', 'contains', ['course-a']).get();

datastore.collection('students')
.where('courses', 'contains', ['course-a','course-b']).get();

Student document course array DOES NOT contain ALL given course(s):

datastore.collection('students')
.where('courses', 'not-contains', 'course-a').get();

datastore.collection('students')
.where('courses', 'not-contains', ['course-a']).get();

datastore.collection('students')
.where('courses', 'not-contains', ['course-a','course-b']).get();

Student document course array contains ANY of the given course(s):

datastore.collection('students')
.where('courses', 'contains-any', 'course-a').get();

datastore.collection('students')
.where('courses', 'contains-any', ['course-a']).get();

datastore.collection('students')
.where('courses', 'contains-any', ['course-a','course-b']).get();

Student document course array DOES NOT contain ANY given course(s):

datastore.collection('students')
.where('courses', 'not-contains-any', 'course-a').get();

datastore.collection('students')
.where('courses', 'not-contains-any', ['course-a']).get();

datastore.collection('students')
.where('courses', 'not-contains-any', ['course-a','course-b']).get();
