RowKeyRegexFilter(regex: str | bytes)

Row filter for a row key regular expression.

The regex must be valid RE2 patterns. See Google's RE2 reference_ for the accepted syntax.

.. _RE2 reference: https://github.com/google/re2/wiki/Syntax

Note: Special care need be used with the expression used. Since each of these properties can contain arbitrary bytes, the \C escape sequence must be used if a true wildcard is desired. The . character will not match the new line character \n, which may be present in a binary value.

Parameter
Name	Description
regex	bytes A regular expression (RE2) to match cells from rows with row keys that satisfy this regex. For a CheckAndMutateRowRequest, this filter is unnecessary since the row key is already specified.
