Then, requesting, by a transaction of the compute node, a lock of a page to be modified by the transaction where the page is part of the page store including a plurality of pages and the transaction is configured to write a data amount to a log. Also, granting, by a lock manager of the compute node, the lock and determining, by the compute node, that the data amount exceeds the log writing quota. Furthermore, releasing, by the transaction, the lock, and throttling, by the compute node, the transaction until a criteria is fulfilled.
