I have an old database containing some deprecated
undefined
values that break queries. I do not want to modify the data.I considered adding support for BSON_TYPE_UNDEFINED but this is a simpler, more general solution. It gives users the option of converting BSONUnsupported(BSON_TYPE_UNDEFINED) to missing or nothing.
It will allow BSON_TYPE_REGEX values (which are unsupported, not deprecated) to not break queries, though the data is lost. It would be nice to be able to use Julia regex in queries...
