Class GoogleRE2
Google's RE2 _ regex engine. The regex string must adhere to the documented syntax _. The engine is designed
to complete execution in linear time as well as limit the amount of memory used. Envoy supports program size
checking via runtime. The runtime keys re2.max_program_size.error_level and
re2.max_program_size.warn_level can be set to integers as the maximum program size or complexity that a
compiled regex can have before an exception is thrown or a warning is logged, respectively.
re2.max_program_size.error_level defaults to 100, and re2.max_program_size.warn_level has no default if
unset (will not check/log a warning). Envoy emits two stats for tracking the program size of regexes: the
histogram re2.program_size, which records the program size, and the counter re2.exceeded_warn_level,
which is incremented each time the program size exceeds the warn level threshold.

MaxProgramSize
This field controls the RE2 "program size" which is a rough estimate of how complex a compiled regex is to
evaluate. A regex that has a program size greater than the configured value will fail to compile. In this
case, the configured max program size can be increased or the regex can be simplified. If not specified, the
default is 100. This field is deprecated; regexp validation should be performed on the management server
instead of being done by each individual client. .. note:: Although this field is deprecated, the program
size will still be checked against the global re2.max_program_size.error_level runtime value.
