Example 1 with RequestMetadata

use of org.apache.kafka.server.policy.AlterConfigPolicy.RequestMetadata in project kafka by apache.

the class ConfigurationControlManager method validateAlterConfig.

private ApiError validateAlterConfig(ConfigResource configResource, List<ApiMessageAndVersion> newRecords, Consumer<ConfigResource> existenceChecker) {
    Map<String, String> newConfigs = new HashMap<>();
    TimelineHashMap<String, String> existingConfigs = configData.get(configResource);
    if (existingConfigs != null)
        newConfigs.putAll(existingConfigs);
    for (ApiMessageAndVersion newRecord : newRecords) {
        ConfigRecord configRecord = (ConfigRecord) newRecord.message();
        if (configRecord.value() == null) {
            newConfigs.remove(configRecord.name());
        } else {
            newConfigs.put(configRecord.name(), configRecord.value());
        }
    }
    try {
        validator.validate(configResource, newConfigs);
        existenceChecker.accept(configResource);
        if (alterConfigPolicy.isPresent()) {
            alterConfigPolicy.get().validate(new RequestMetadata(configResource, newConfigs));
        }
    } catch (ConfigException e) {
        return new ApiError(INVALID_CONFIG, e.getMessage());
    } catch (Throwable e) {
