The parameters affect high level (not column type related) simulation settings such as target number of rows for each table. Currently only number of simulated rows is supported.
opt_default_table(nrows = nrows_simul_constant(10))Integer or function. When nrows is precised as an integer value,
all the tables will have the same number of rows.
In case of function, the should take tables configuration (list of tables section
from configuration YSML file) and return named list of table with rows values.
See nrows_simul_constant and nrows_simul_ratio for more details.
