That would great yes. The field name may not be sufficient though, the location relative to the schema root would be better I think. Internally we have defined a simple spec we call avroloc that looks like recorda.field1.field2.1.recordb.field3 where the numeric step .1 is the zero-based alternative in case you traverse a union. To signal a particular item in an array, field2[3] is used in the avroloc. While we are on the topic of read error reporting, record number and offset within the record where the offending data is would also help. Fady
