Methods

batchReadOnlyTransaction(BatchTransactionId batchTransactionId)

public BatchReadOnlyTransaction batchReadOnlyTransaction(BatchTransactionId batchTransactionId)

Returns a BatchReadOnlyTransaction context in which multiple reads and/or queries can be performed. This is a non-blocking method. All reads/queries will use the same timestamp, and the timestamp can be inspected after this transaction is created successfully.

This method is useful to recreate a BatchReadOnlyTransaction object from an existing batchTransactionId. For example one might send the transaction id to a different process or machine and recreate the transaction object there.

Parameter
Name	Description
`batchTransactionId`	`BatchTransactionId`

Returns
Type	Description
`BatchReadOnlyTransaction`

batchReadOnlyTransaction(TimestampBound bound)

public BatchReadOnlyTransaction batchReadOnlyTransaction(TimestampBound bound)

Returns a BatchReadOnlyTransaction context in which multiple reads and/or queries can be performed. All reads/queries will use the same timestamp, and the timestamp can be inspected after this transaction is created successfully. This is a blocking method since it waits to finish the rpcs.

Note that the bounded staleness modes, TimestampBound.Mode#MIN_READ_TIMESTAMP and TimestampBound.Mode#MAX_STALENESS, are not supported for BatchReadOnlyTransaction.

Parameter
Name	Description
`bound`	`TimestampBound`

Returns
Type	Description
`BatchReadOnlyTransaction`

getDatabaseRole()

public String getDatabaseRole()

Returns the DatabaseRole used by the client connection. The database role that is used determines the access permissions that a connection has. This can for example be used to create connections that are only permitted to access certain tables.

Returns
Type	Description
`String`
