Explore Seata 1.5: New Enterprise Features, SkyWalking Integration, and YAML Config

1. Seata 1.5 New Features

After a year of waiting, Seata 1.5 is released; the Pig microservice framework already supports version 1.5.

① Stronger Seata Enterprise Edition

Alibaba Cloud's Seata Enterprise edition is now in public beta, offering fully managed service and a more stable kernel than the open‑source version. Compared with the open‑source kernel, the enterprise version reduces latency (rt) by over 20% and increases TPS by 30%; overall performance for the same specifications is expected to improve by about 100%+. It also resolves transaction “spike” issues in high‑concurrency scenarios.

② Graphical Console

Online transaction information

Supports DB, Redis, File modes

Note: the console default port is 7091

③ SkyWalking Transaction Tracing Support

apm-seata-skywalking-plugin-1.5.1.jar

Logs now print both XID and TraceId, allowing you to input the TraceId in SkyWalking to trace the global transaction chain; Seata monitoring integrates with SkyWalking dashboards, topology, profiling, and alerts.

④ YAML Configuration for seata‑server

Since version 1.5, all Seata configuration can be done via application.yml.

2. Quick Introduction to Seata Distributed Transactions

Using Seata in Pig

① Deploy seata‑server

Download seata-server-1.5.1.zip and unzip.

# windows
seata-server.bat -p 8091 -h 127.0.0.1 -m file
# mac or linux
sh seata-server.sh -p 8091 -h 127.0.0.1 -m file

② Add Dependency

<dependency>
    <groupId>com.pig4cloud</groupId>
    <artifactId>pig-common-seata</artifactId>
</dependency>

③ Declare @GlobalTransactional on Service Caller

@GlobalTransactional // distributed transaction annotation
@Transactional(rollbackFor = Exception)
public R consumer() {
    feign.providerMethod(); // call provider service via Feign
}

④ Add undo_log Table for Microservice Databases

CREATE TABLE `undo_log` (
  `id` bigint(20) NOT NULL AUTO_INCREMENT,
  `branch_id` bigint(20) NOT NULL,
  `xid` varchar(100) NOT NULL,
  `context` varchar(128) NOT NULL,
  `rollback_info` longblob NOT NULL,
  `log_status` int(11) NOT NULL,
  `log_created` datetime NOT NULL,
  `log_modified` datetime NOT NULL,
  `ext` varchar(100) DEFAULT NULL,
  PRIMARY KEY (`id`),
  UNIQUE KEY `ux_undo_log` (`xid`,`branch_id`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;
