Re: UUID Logical type not working in Java
Thanks Martin for the quick response, I will give it a try and let you know. I tried with 1.11.0 earlier.

Re: UUID Logical type not working in Java
Hi, Which version of Avro do you use ? Which language ? If Java, then please try 1.12.0-SNAPSHOT from https://repository.apache.org/content/groups/snapshots/ If it still does not work then please show us your schema or even better create a reproducer and share it with us, e.g. at Github.

UUID Logical type not working in Java
Hello All, I'm trying to use uuid logical type in one of my AVRO schema with string as avro type. The generated class has the field type as string but I'm expecting it to be UUID, is this a known issue? It works for other logical types local-timestamp-millis as an example. Appreciate your help in advance. Thanks, Swamy Thota
Re: Papers discussing Apache Avro
This is really cool news -- it's always really interesting to see benchmark studies and the trade-offs we make while choosing different formats. Thanks for sharing! I'd love to see links to some curated articles and papers on the website! I created AVRO-3308 if you don't object :D Ryan On Fri, Jan 14, 2022 at 10:49 AM Martin Grigorov wrote: > > Hi Juan, > > Thank you for sharing your work with us! > > It comes right in time for me! > I am working on the interop tests for the new Rust module and it seems there > is some problem to read the .avro files generated by Java.

Re: Papers discussing Apache Avro
Hi Juan, Thank you for sharing your work with us! It comes right in time for me! I am working on the interop tests for the new Rust module and it seems there is some problem to read the .avro files generated by Java. I may need to dive in the binary diffs.
