Mammoth transactions, which involve long-running operations that access many items, are common in graph workloads. Graph analytics tasks, including pattern matching and graph algorithms, can generate large read-write operations that impact signi!cant …
In this paper, we describe No-Wait concurrency control mechanisms to address conflict resolution and then comprehensively evaluate their performance under Read-Committed and Serializability isolation levels using an in-memory database system in …
A model of a large distributed database, where write conflicts are handled by wait-free aborting of transactions, is introduced. and analysed in the steady state. Performance measures, including the rate of aborts, are evaluated. Numerical results …
