Browsing through src code, saw below line in https://github.com/stellar/stellar-core/tree/master/src/database "The Database object manages connections to an SQL database, in which the current ledger state and several auxiliary tables are stored."

Am trying to understand requirements realted to sharding, load-balancing, failover, backups and other database related adminstrative tasks for a basic/full validator node.

Post How big is the ledger? lists ledger count as of Jan 18 as 15734806

Will each transaction in stellar, result in a row in the SQL database table?.

Any thoughts on database adminstration requirments related to stellar?
