Cloud System Benchmark # Workload D: Read latest workload # Application example: user status updates; people want to read the latest # # Read/update/insert ratio: 95/0/5 # Default data size: 1 KB records (10 fields, 100 bytes each, plus key) # Request distribution: latest # The insert order for this is hashed, not ordered. The "latest" items may be # scattered around the keyspace if they are keyed by userid.timestamp. A workload # which orders items purely by time, and demands the latest, is very different than # workload here (which we believe is more typical of how people build systems.) recordcount=1000 operationcount=1000 workload=com.yahoo.ycsb.workloads.CoreWorkload readallfields=true readproportion=0.95 updateproportion=0 scanproportion=0 insertproportion=0.05 requestdistribution=latest
