Enhance wtperf to support periodic table scans

    • Storage 2017-02-13

      It would be useful in reproducing workloads to be able to schedule a large table scan that happens occasionally. Especially in mutli-table workloads.

      The configuration string I'm thinking is:

      threads=((count=20,reads=1),(count=5,updates=1,throttle=100),(count=1,scan=1000000,pause=300,table_name=test00003))
      

      The new options are:

      • scan Number of items to iterate over
      • pause How many seconds to wait between scans
      • table_name The name of the table (in multi-table workloads) that will be scanned

      The scan operation would start at a random point in the specified tree (or the first/only tree if no explicit value is specified) and walk until it has either visited the count of values or reaches the end of the tree.
