Support background index #15603

Open kwannoel opened 6 months ago

An interesting usecase for background ddl is that we can use it for transient errors.

Typically in foreground ddl, if there's some transient error, the entire stream job will fail.

But with background ddl, since the stream job is persisted, after recovery it can continue execution.
