options

getLockTimeout

public Integer getLockTimeout()

lockTimeout

public TransactionOptions lockTimeout(Integer lockTimeout)

Parameters:

lockTimeout - a numeric value that can be used to set a timeout in seconds for waiting on collection locks. This option is only meaningful when using exclusive locks. If not specified, a default value of 900 seconds will be used. Setting lockTimeout to 0 will make ArangoDB not time out waiting for a lock.

Returns:

options

getWaitForSync

public Boolean getWaitForSync()

waitForSync

public TransactionOptions waitForSync(Boolean waitForSync)

Parameters:

waitForSync - an optional boolean flag that, if set, will force the transaction to write all data to disk before returning

Returns:

options

readCollections

public TransactionOptions readCollections(String... read)

Parameters:

read - contains the array of collection-names to be used in the transaction (mandatory) for read

Returns:

options

writeCollections

public TransactionOptions writeCollections(String... write)

Parameters:

write - contains the array of collection-names to be used in the transaction (mandatory) for write

Returns:

options

exclusiveCollections

public TransactionOptions exclusiveCollections(String... exclusive)

Parameters:

exclusive - contains the array of collection-names to be used in the transaction (mandatory) for exclusive write

Returns:

options

Since:

ArangoDB 3.4.0

allowImplicit

public TransactionOptions allowImplicit(Boolean allowImplicit)

Parameters:

allowImplicit - Collections that will be written to in the transaction must be declared with the write attribute or it will fail, whereas non-declared collections from which is solely read will be added lazily. The optional attribute allowImplicit can be set to false to let transactions fail in case of undeclared collections for reading. Collections for reading should be fully declared if possible, to avoid deadlocks.

Returns:

options

getMaxTransactionSize

public Long getMaxTransactionSize()

maxTransactionSize

public TransactionOptions maxTransactionSize(Long maxTransactionSize)

Parameters:

maxTransactionSize - Transaction size limit in bytes. Honored by the RocksDB storage engine only.

Returns:
