# Which Problems Are Solved
Group attributes weren't masked if their corresponding key was
configured. For example setting `data` as a masked key entry in the
runtime config would still print unmasked event data. This was because
ReplaceAttr does not receive group attributes, only the flattened
attributes with group information.
# How the Problems Are Solved
Check the current groups stack in the replacer. When a configured key is
found in the group, mask the current attribute. This means that the
attribute structure is preserved and all sub-keys of a masked group are
still printed.
# Additional Changes
- Use a binary search for key matching. As we are now comparing slice
against slice, a binary search should make the process a little faster
if many keys are configured.
# Additional Context
- Follow-up for PR #11435
