$ zig build fuzz -- ledger_rocksdb 10 1_000_000 > output.txt 2>&1
$ grep -c 'Put actions' output.txt
890
$ grep -c 'Delete actions' output.txt
889
$ grep -c 'Delete Files in Range actions' output.txt
925
$ grep -c 'getBytes actions' output.txt
10
$ grep -c 'get actions' output.txt
11
$ grep -c 'count actions' output.txt
997
$ grep -c 'contains actions' output.txt
11
$ grep -c 'Batch actions' output.txt
904

get, getBytes and contains are order of magnitude slower. Need to investigate

Update: Only running the get and getBytes leads to

$ grep -c 'get actions' output.txt
988
$ grep -c 'getBytes actions' output.txt
978

Update: This is related to try batch.deleteRange(cf1, start, end);. It seems deleteRange call negatively impacts the get calls. This would be investigated in a follow up PR.
