Examples with DataNodeService org.apache.druid.discovery.DataNodeService used on opensource projects

Example 1 with DataNodeService

use of org.apache.druid.discovery.DataNodeService in project druid by druid-io.

the class DruidServiceSerializer method serializeWithType.

@Override
public void serializeWithType(DruidService druidService, JsonGenerator gen, SerializerProvider serializers, TypeSerializer typeSer) throws IOException {
    if (druidService instanceof DataNodeService) {
        DataNodeService dataNodeService = (DataNodeService) druidService;
        gen.writeStartObject();
        // Write subtype key first. This is important because Jackson picks up the first "type" field as the subtype key
        // for deserialization.
        gen.writeStringField("type", DataNodeService.DISCOVERY_SERVICE_KEY);
        // Write properties of DataNodeService
        gen.writeStringField("tier", dataNodeService.getTier());
        gen.writeNumberField("maxSize", dataNodeService.getMaxSize());
        // NOTE: the below line writes a duplicate key of "type".
        // This is a bug that DataNodeService has a key of the same name as the subtype key.
        // To address the bug, a new "serverType" field has been added.
        // However, we cannot remove the deprecated "type" entirely yet because it will break rolling upgrade.
        // It seems OK to have duplicate keys though because Jackson seems to always pick up the first "type" property
        // as the subtype key for deserialization.
        // This duplicate key should be removed in a future release.
        // See DiscoveryDruidNode.toMap() for deserialization of DruidServices.
        gen.writeObjectField("type", dataNodeService.getServerType());
        gen.writeObjectField("serverType", dataNodeService.getServerType());
        gen.writeNumberField("priority", dataNodeService.getPriority());
