Consensus protocols such as Raft and Paxos implement state machine replication through a single leader that enforces a totally ordered log. While this simplifies correctness, it introduces sequential bottlenecks that restrict scalability. We present …
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 …
B+Trees are widely used as persistent index implementations for databases. They are often implemented in a way that allows the index to be in main memory while the indexed data remains on disk. Over the years, multiple optimization techniques have …
