Asynchronous Ledger Demo
========================
Author: Eitan Blumin | https://eitanblumin.com | https://madeiradata.com
Date: 2021-07-03
Description:
This script demonstrates a use case of a high-throughput table
which serves as a "hot-spot" for inserts and updates and queries.
This causes performance problems due to long lock chains, possible deadlocks,
and sometimes even worker thread starvation.

Description:
This is the simplest possible alternative to sp_MSforeachdb which is not too great.
Instructions:
1. Replace the contents of the @Command variable with the command you want to run INSIDE each database.
2. Replace the contents of the @Parameters variable with the parameters you want the command to receive.
3. Add parameters as needed, given @p1 as an example.
4. Change the database filter predicates in the cursor declaration, as needed.
