Method Summary

Modifier and Type	Method and Description
Mono<Void>	beginTransaction()
Mono<Void>	beginTransaction(io.r2dbc.spi.TransactionDefinition definition)
Mono<Void>	close()
Mono<Void>	commitTransaction()
MySqlBatch	createBatch()
Mono<Void>	createSavepoint(String name)
MySqlStatement	createStatement(String sql)
MySqlConnectionMetadata	getMetadata()
io.r2dbc.spi.IsolationLevel	getTransactionIsolationLevel() MySQL does not have any way to query the isolation level of the current transaction, only inferred from past statements, so driver can not make sure the result is right.
boolean	isAutoCommit()
boolean	isInTransaction() Checks if connection is processing a transaction.
boolean	isLockWaitTimeoutChanged() Checks if lock wait timeout has been changed by setCurrentLockWaitTimeout(long).
Mono<Void>	releaseSavepoint(String name)
void	resetCurrentLockWaitTimeout() Resets current isolation level in initial state.
void	resetIsolationLevel() Resets current isolation level in initial state.
Mono<Void>	rollbackTransaction()
Mono<Void>	rollbackTransactionToSavepoint(String name)
Mono<Void>	setAutoCommit(boolean autoCommit)
void	setCurrentLockWaitTimeout(long timeoutSeconds) Sets current lock wait timeout.
void	setIsolationLevel(io.r2dbc.spi.IsolationLevel level) Sets current isolation level.
Mono<Void>	setLockWaitTimeout(Duration timeout)
Mono<Void>	setStatementTimeout(Duration timeout)
Mono<Void>	setTransactionIsolationLevel(io.r2dbc.spi.IsolationLevel isolationLevel)
