max_rand_* session settings

ClickHouse session settings in the max_rand_* generated group.

These settings are available in system.settings and are autogenerated from source.

max_rand_distribution_parameter

Maximum value for distribution shape parameters in random distribution functions such as randChiSquared, randStudentT, and randFisherF. This prevents extremely long computation times with extreme parameter values. 0 disables the limit; values for which the sampler does not terminate at all are still rejected.

max_rand_distribution_trials

Maximum number of trials allowed for random distribution functions such as randBinomial and randNegativeBinomial. This prevents extremely long computation times with large trial counts. 0 disables the limit, and the setting may be raised above its default, except for randBinomial, which always rejects more than 10^9 trials because the cost of a single sample is proportional to the number of trials in the worst case, with a probability that grows with it.
