Examples with SchemaValidator org.apache.avro.SchemaValidator used on opensource projects

Example 1 with SchemaValidator

use of org.apache.avro.SchemaValidator in project hopsworks by logicalclocks.

the class SubjectsController method isCompatible.

private boolean isCompatible(Project project, String subject, Schema schema) throws SchemaException {
    SchemaCompatibility sc = getSubjectOrProjectCompatibility(project, subject);
    if (sc.equals(SchemaCompatibility.NONE)) {
        return true;
    }
    SchemaValidator validator = getSchemaValidator(sc);
    List<Schema> previousSchemas = subjectsFacade.findSubjectByName(project, subject).stream().sorted(Comparator.comparing(Subjects::getVersion).reversed()).map(s -> new Schema.Parser().parse(s.getSchema().getSchema())).collect(Collectors.toList());
    try {
        validator.validate(schema, previousSchemas);
    } catch (SchemaValidationException e) {
        return false;
    }
    return true;
}

Example 2 with SchemaValidator

use of org.apache.avro.SchemaValidator in project apicurio-registry by Apicurio.

the class AvroCompatibilityChecker method testCompatibility.

/**
 * @see CompatibilityChecker#testCompatibility(io.apicurio.registry.rules.compatibility.CompatibilityLevel, java.util.List, java.lang.String)
 */
@Override
public CompatibilityExecutionResult testCompatibility(CompatibilityLevel compatibilityLevel, List<String> existingSchemaStrings, String proposedSchemaString) {
    requireNonNull(compatibilityLevel, "compatibilityLevel MUST NOT be null");
    requireNonNull(existingSchemaStrings, "existingSchemaStrings MUST NOT be null");
    requireNonNull(proposedSchemaString, "proposedSchemaString MUST NOT be null");
    SchemaValidator schemaValidator = validatorFor(compatibilityLevel);
    if (schemaValidator == null) {
        return CompatibilityExecutionResult.compatible();
    }
    try {
        List<Schema> existingSchemas = existingSchemaStrings.stream().map(s -> new Schema.Parser().parse(s)).collect(Collectors.toList());
        // the most recent must come first, i.e. reverse-chronological.
        Collections.reverse(existingSchemas);
        Schema toValidate = new Schema.Parser().parse(proposedSchemaString);
        schemaValidator.validate(toValidate, existingSchemas);
        return CompatibilityExecutionResult.compatible();
    } catch (SchemaValidationException e) {
        return CompatibilityExecutionResult.incompatible(e);
    } catch (SchemaParseException | AvroTypeException e) {
        throw new UnprocessableSchemaException(e.getMessage());
