/* these could have been properties with getters that just returned data based on URl,
but they are used in rowafter event and while the getters are very fast, overrided getters
are still 20 times slower than variables/props with no overrides. We're talking milliseconds, but
enough to substantially reduce throughput for this datasource, which may need to read a lot of records
