Abstract: Client systems of a distributed database system manage execution of transactions on data stored within the distributed database system. The client systems communicate directly with database nodes of the distributed database system in order to manage transactions. The client systems interact with the database nodes of the distributed database system via a client-side interface that performs various operations to execute transactions at the distributed database nodes, including retrieving records, staging mutations or insertions, committing mutations or insertions, or rolling back mutations or insertions on records stored on the distributed database nodes. Interactions between the client-side interface and the database nodes of the distributed database system are further configured to prevent conflicts between different transactions executed by the same or different client systems at the database nodes.

Abstract: A distributed database system for handling transactions from multiple client systems. A database node receives a request to execute a transaction from a first client, involving a record modification. This record has an associated check-and-set (CAS) value that changes with modifications. The record is sent to the first client, which identifies the CAS value. Similarly, a second client sends a request for another transaction, receives the record, and identifies the CAS value. One of these clients attempts to stage a mutation based on their transaction. This includes sending the previously received CAS value. The system checks for a CAS value mismatch, indicating a conflicting mutation from another transaction. If a mismatch is detected, the transaction attempt is aborted to prevent conflicts. Otherwise, the mutation is staged, and the CAS value is updated.
