Google's `RE2 <https://github.com/google/re2>`_ regex engine. The regex string must adhere to the documented `syntax <https://github.com/google/re2/wiki/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.Protobuf type

hasMaxProgramSize
Deprecated.envoy.type.matcher.v3.RegexMatcher.GoogleRE2.max_program_size is deprecated. See envoy/type/matcher/v3/regex.proto;l=53This 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.
.google.protobuf.UInt32Value max_program_size = 1 [deprecated = true, (.envoy.annotations.deprecated_at_minor_version) = "3.0"];
