Examples of DetachedTxSystemClient

co.cask.tephra.inmemory.DetachedTxSystemClient

Implementation of the tx system client that doesn't talk to any global service and tries to do its best to meet the tx system requirements/expectations. In fact it implements enough logic to support running flows (when each flowlet uses its own detached tx system client, without talking to each other and sharing any state) with "process exactly once" guarantee if no failures happen. NOTE: Will NOT detect conflicts. May leave inconsistent state when process crashes. Does NOT provide even read isolation guarantees. Good for performance testing. For demoing high throughput. For use-cases with relaxed tx guarantees.
