Reading about HA & load balancing for RStudio Package Manager here https://docs.rstudio.com/rspm/admin/high-availability.html
" 1. HA requires using a PostgreSQL database. All nodes in the cluster must use the same PostgreSQL database."
It seems for HA PostgreSQL DB is a must. Challenge is if an Open source technology is not already an approved standard for the organization it is extremely challenging and time-consuming to either get a waiver or to standardize it.
Hence, I am wondering if there is a way to implement HA for Package Manager with any other DBs i.e. SQL Server, Oracle DB, MongoDB, MySQL etc.
Thank you in advance for your response.
