Seriously?? A big 3.0.0 update to this feature was a bit of a surprise.
ElasticJob 3.0.0 also includes a number of kernel refactoring and decoupling enhancements, as well as a number of ecological docking enhancements, such as out-of-the-box enterprise wechat and pin job error notifications.
conclusion
ElasticJob 3.0.0 isn’t a big surprise, but it’s a big step forward. I haven’t been looking at ElasticJob for a while, but I don’t recommend it for now.
ElasticJob 2. X is the only version of ElasticJob that can be used by large companies.
Companies known to adopt can see here:
Shardingsphere.apache.org/elasticjob/…
ElasticJob has been used by the same company as ElasticJob, and has been customizing some of the ElasticJob features. I think it’s ok. Sharding and automatic failover are very powerful.
