generatejournal.hs NUMTXNS NUMACCTS ACCTDEPTH [--chinese|--mixed]
|
|
|
|
This generates synthetic journal data for benchmarking & profiling. It
|
|
prints a dummy journal on stdout, with NUMTXNS transactions, one per
|
|
day, using NUMACCTS account names with depths up to ACCTDEPTH. It will
|
|
also contain NUMACCTS P records, one per day. By default it uses only
|
|
ascii characters, with --chinese it uses wide chinese characters, or
|
|
with --mixed it uses both.
