Method Detail

getReftableConfig

public ReftableConfig getReftableConfig()

Description copied from class: DfsReftableDatabase

Get configuration to write new reftables with.

Overrides:

getReftableConfig in class DfsReftableDatabase

Returns:

configuration to write new reftables with.

performsAtomicTransactions

public boolean performsAtomicTransactions()

Description copied from class: DfsReftableDatabase

Whether the database is capable of performing batch updates as atomic transactions.

If true, by default BatchRefUpdate instances will perform updates atomically, meaning either all updates will succeed, or all updates will fail. It is still possible to turn off this behavior on a per-batch basis by calling update.setAtomic(false).

If false, BatchRefUpdate instances will never perform updates atomically, and calling update.setAtomic(true) will cause the entire batch to fail with REJECTED_OTHER_REASON.

This definition of atomicity is stronger than what is provided by ReceivePack. ReceivePack will attempt to reject all commands if it knows in advance some commands may fail, even if the storage layer does not support atomic transactions. Here, atomicity applies even in the case of unforeseeable errors.

Overrides:

performsAtomicTransactions in class DfsReftableDatabase

Returns:

whether transactions are atomic by default.
