Durable database log system with low-latency transactions stored across multiple storage nodes

A system, comprising:

• a transaction management component;
• a plurality of storage management nodes;
• and
• a plurality of nodes configured to implement logs respectively associated with respective ones of the plurality of storage management nodes;
• wherein the transaction management component is configured to:
• receive a transaction comprising an intended change to be performed for a dataset;
• cause the transaction to be distributed to a set of the plurality of storage management nodes managing data of the dataset implicated by the change, wherein the respective storage management nodes of the set cause the transaction to be logged at respective logs that are respectively associated with the respective storage management nodes of the set;
• receive, from the storage management nodes of the set of the plurality of storage management nodes managing the data of the dataset implicated by the change, acknowledgements the transaction has been written in relevant ones of the respective logs associated with the respective storage management nodes of the set of the plurality of storage management nodes managing the data of the dataset implicated by the change;
• and
• provide, in response to receiving the acknowledgments from the storage management nodes of the set, a response that the transaction has been committed,
• wherein the transaction management component provides the response in response to receiving the acknowledgments without waiting for a summary entry of the acknowledgements to be written.
