Adds DynamoDBExpressionVisitor that translates GraphQL filter ASTs into DynamoDB FilterExpression strings with a corresponding ExpressionAttributeValues map. Registers DYNAMODB in ExpressionFormat and ExpressionVisitorFactory. Operator mappings: - CONTAINS → contains(field, :field) - STARTS → begins_with(field, :field) - EQ/EQUALS → field = :field - GT/GTE → field > / >= :min_field - LT/LTE → field < / <= :max_field - IN → field IN (:field_0, :field_1, ...) - BETWEEN → field BETWEEN :min_field AND :max_field - NOT → ( NOT (...)) - AND/OR → compound with parentheses for precedence Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Adds AFTER, BEFORE, ON_OR_AFTER, ON_OR_BEFORE, ON date operators to Operator.java, mirroring the internal graphql-query-filters implementation. Updates DynamoDBExpressionVisitor to map these to the correct DynamoDB comparison operators and :min_/:max_ parameter naming convention. Also extends the test schema's DateExpression and adds 5 date operator test cases to DynamoDBExpressionTest. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
This reverts commit 859a623.
- Add DynamoDB FilterExpression to Supported Formats and Databases sections - Add DynamoDB usage section with code example and operator mapping table - Update Schema section to include DateExpression and full StringExpression/IntExpression operators Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
