[DocDb] Optimize deadlock detection to detect conflicts local to tserver when present #13586

Open robertsami opened 2 years ago

robertsami commented 2 years ago

Jira Link: DB-3162 We can detect some deadlocks without relying on distributed deadlock detection by just looking at local wait-for relationships. We can do this for a new waiting transaction /before/ sending information about this waiting transaction to the txn coordinator

This is important, if the performance impact of deadlock detection is high and if there is a need to reduce it.
