Trace output limit
CONFIG PARAMETER: trace_output_limit <amount>
Specifies the maximum number of lines of trace output that will be displayed when using top-down format. Bottom-up format output is not affected by this parameter. Direction of trace output is controlled by the trace_topdown parameter.
Note that this parameter is intended as a limit on the amount of memory used to store intermediate data and not on the quantity of trace output, top-down format needs to keep all intermediate results in memory before displaying them, while bottom-up format displays them immediately after generating them.
When trace output lines are discarded, only the last <amount> lines are kept. These lines contain information about the evaluations done earliest in the process of evaluating the expression (usually the innermost evaluations and earlier arguments of outer functions).
