Package avro provides encoding and decoding for the Avro binary data format. The format uses out-of-band schemas to determine the encoding, with a schema migration scheme to allow data written with one schema to be read using another schema. See here for more information on the format: https://avro.apache.org/docs/1.9.1/spec.html This package provides a mapping from regular Go types to Avro schemas. See the TypeOf function for more details. There is also a code generation tool that can generate Go data structures from Avro schemas. See https://pkg.go.dev/github.com/heetch/avro/cmd/avrogo for details.
