springcloud中的服务链路追踪，之前我们已经讲过一次了，在实际应用中，我们经常需要将链路服务的记录保存下来，以实现服务的监测和分析，那么这就需要用到数据库了。下面我们来实现一下。数据库表结构：

CREATE TABLE `zipkin_annotations` (
      `trace_id_high` bigint(20) NOT NULL DEFAULT '0' COMMENT 'If non zero, this means the trace uses 128 bit traceIds instead of 64 bit',
      `trace_id` bigint(20) NOT NULL COMMENT 'coincides with zipkin_spans.trace_id',
      `span_id` bigint(20) NOT NULL COMMENT 'coincides with zipkin_spans.id',
      `a_key` varchar(255) NOT NULL COMMENT 'BinaryAnnotation.key or Annotation.value if type == -1',
      `a_value` blob COMMENT 'BinaryAnnotation.value(), which must be smaller than 64KB',
      `a_type` int(11) NOT NULL COMMENT 'BinaryAnnotation.type() or -1 if Annotation',
      `a_timestamp` bigint(20) DEFAULT NULL COMMENT 'Used to implement TTL; Annotation.timestamp or zipkin_spans.timestamp',
      `endpoint_ipv4` int(11) DEFAULT NULL COMMENT 'Null when Binary/Annotation.endpoint is null',
      `endpoint_ipv6` binary(16) DEFAULT NULL COMMENT 'Null when Binary/Annotation.endpoint is null, or no IPv6 address',
      `endpoint_port` smallint(6) DEFAULT NULL COMMENT 'Null when Binary/Annotation.endpoint is null',
      `endpoint_service_name` varchar(255) DEFAULT NULL COMMENT 'Null when Binary/Annotation.endpoint is null',
      UNIQUE KEY `trace_id_high` (`trace_id_high`,`trace_id`,`span_id`,`a_key`,`a_timestamp`) COMMENT 'Ignore insert on duplicate',
      KEY `trace_id_high_2` (`trace_id_high`,`trace_id`,`span_id`) COMMENT 'for joining with zipkin_spans',
      KEY `trace_id_high_3` (`trace_id_high`,`trace_id`) COMMENT 'for getTraces/ByIds',
      KEY `endpoint_service_name` (`endpoint_service_name`) COMMENT 'for getTraces and getServiceNames',
      KEY `a_type` (`a_type`) COMMENT 'for getTraces',
      KEY `a_key` (`a_key`) COMMENT 'for getTraces'
    ) ENGINE=InnoDB DEFAULT CHARSET=utf8 ROW_FORMAT=COMPRESSED
    
    CREATE TABLE `zipkin_dependencies` (
      `day` date NOT NULL,
      `parent` varchar(255) NOT NULL,
      `child` varchar(255) NOT NULL,
      `call_count` bigint(20) DEFAULT NULL,
      `error_count` bigint(20) DEFAULT NULL,
      UNIQUE KEY `day` (`day`,`parent`,`child`)
    ) ENGINE=InnoDB DEFAULT CHARSET=utf8 ROW_FORMAT=COMPRESSED
    
    
    CREATE TABLE `zipkin_spans` (
      `trace_id_high` bigint(20) NOT NULL DEFAULT '0' COMMENT 'If non zero, this means the trace uses 128 bit traceIds instead of 64 bit',
      `trace_id` bigint(20) NOT NULL,
      `id` bigint(20) NOT NULL,
      `name` varchar(255) NOT NULL,
      `parent_id` bigint(20) DEFAULT NULL,
      `debug` bit(1) DEFAULT NULL,
      `start_ts` bigint(20) DEFAULT NULL COMMENT 'Span.timestamp(): epoch micros used for endTs query and to implement TTL',
      `duration` bigint(20) DEFAULT NULL COMMENT 'Span.duration(): micros used for minDuration and maxDuration query',
      UNIQUE KEY `trace_id_high` (`trace_id_high`,`trace_id`,`id`) COMMENT 'ignore insert on duplicate',
      KEY `trace_id_high_2` (`trace_id_high`,`trace_id`,`id`) COMMENT 'for joining with zipkin_annotations',
      KEY `trace_id_high_3` (`trace_id_high`,`trace_id`) COMMENT 'for getTracesByIds',
      KEY `name` (`name`) COMMENT 'for getTraces and getSpanNames',
      KEY `start_ts` (`start_ts`) COMMENT 'for getTraces ordering and range'
    ) ENGINE=InnoDB DEFAULT CHARSET=utf8 ROW_FORMAT=COMPRESSED
