Research direction

The issue names no files, tests, or entry points. Start by reviewing the existing dimension-table join and Oracle access paths, then determine whether shared data across jobs is supported; done would require an agreed mechanism that reduces duplicate storage and database session or concurrency pressure.

Description

您 好！
请问是否可以提供 维表数据共享机制，这样不同的JOB可以共享维表数据，这样可以在节省
维表数据存多份，同时可以进一步减轻维表数据库的并发访问压力。
当然可能是我的思路有问题，我们发现flinkstreamsql多个任务在访问同一个oracle数据库时还是有不小性能和session占用压力的。所以想看是否有相关机制能多个同类型的JOB共享维表数据，来降低数据库
压力。
