defaultR2dbcIsolationLevel

abstract val defaultR2dbcIsolationLevel: IsolationLevel?

The default transaction IsolationLevel. If not specified, the database-specific level will be used. This can be overridden on a per-transaction level by specifying the transactionIsolation parameter of the org.jetbrains.exposed.v1.r2dbc.transactions.suspendTransaction.

Check R2dbcDatabase.getDefaultIsolationLevel() for the database defaults.
