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?
