we’ve developed a schema with a union of null and a decimal logical type
which avrohugger is able to correctly turn into
Option[BigDecimal]
but it seems that due to this bug, we cannot use avro files with such a field when it’s present with Avro’s Java implementation : https://issues.apache.org/jira/browse/AVRO-1891
has anyone else run into this, and maybe found a workaround?
@adityanahan sorry, no experience personally. However, I recall that avro's java idl parser doesn't support
uuid yet, while the java schema parser does. I wonder if the avro c libraries' parsers support it yet? You may like to troubleshoot by replacing uuid type with string type in your idl or schema
@NJAldwin dang, that's unfortunate. Until that java avro codegen bug is fixed, I don't see a way to share the schema with a java team. I wonder if it may be worth considering losing a little type safety in your schema, and using
string type instead of decimal.
I have tried to put all my types into one avsc like suggested here but it fails with
Unions, beyond nullable fields, are not supported.
I used a field with
union {null, decimal(20, 8)} foo;
it would be great if we could specify the RoundingMode
This is a long shot, but anyone in here using
sbt/sbt-avro? It seems to have just up and vanished from GitHub… https://github.com/sbt/sbt-avro
(we use it in concert with
sbt-avrohugger to generate java and scala from avro schemas)
Hello! I was just trying out avrohugger (looking to introduce it generally to the organization), but am running into a rather confusing error when I try to generate a schema with enums. Do you have any advice?
val schemaStr =
"""
|{
| "type": "record",
| "name": "Employee",
| "fields": [
| {
| "name": "Gender",
| "type": "enum",
| "symbols": [ "male", "female", "non_binary" ]
| }
| ]
|}
|""".stripMargin
val myScalaTypes = Some(Standard.defaultTypes.copy(enum = EnumAsScalaString))
val generator = Generator(Standard, avroScalaCustomTypes = myScalaTypes)
generator.stringToFile(schemaStr)Which throws:
ToolBoxError: reflective compilation has failed:
identifier expected but string literal found.
...
@julien-truffaut if it's still of interest, I was able to reproduce the rounding bug when serializing decimals in SpecificRecords, fixed in RC21 by adding configurable rounding mode e.g.
val myScalaTypes = Some(SpecificRecord.defaultTypes.copy(decimal = ScalaBigDecimal(Some(RoundingMode.HALF_EVEN))))
where does this configuration go?
I see https://repo1.maven.org/maven2/com/julianpeeters/sbt-avrohugger_2.10_0.13/ only goes to 2.0.0-RC15, whereas there is already a -RC21 in more recent scala/sbt versions. was support dropped?
I'm trying to investigate why my logicalType: date and timestamp-millis aren't represented by LocalDate & Instant anymore, between two projects. in my original one it was fine (where I have RC19), but now I'm on an older scala/sbt and they come out as "Long".
@julien-truffaut ah pardon. If you're using the sbt-avrohugger plugin, then here is an example https://github.com/julianpeeters/sbt-avrohugger/blob/master/src/sbt-test/avrohugger/SpecificSerializationTests/build.sbt#L13, or using avrohugger directly would be something like
val generator = Generator(Standard, avroScalaCustomTypes = myScalaTypes), or I'd be curious if you had something else in mind
@jmgpeeters yes, support was dropped for sbt 0.13 around then, because cross-compiling for both 1.0.0 and 0.13 became infeasible. Glad you found a solution
I've googled around and not found anything ... so I'm asking here :) ... I'm trying to produce a sources.jar for the generated code (using sbt-avrohugger and sbt-release) but the <schemaname>_2.12.sources.jar is empty (except for the META-INF/MANIFEST.MF) ... is there a configuration I can add that will fix this?
@danebert I think the keyword you're looking for is
src_managed. Avrohugger generates into that directory by default, in target, intended for source files managed totally by sbt (and thus are excluded from publishing as well). Overriding that is probably a question for sbt, but I wonder if it'll work for you if you configure Avrohugger's output to use a directory in src, e.g. https://github.com/julianpeeters/sbt-avrohugger/blob/master/src/sbt-test/sbt-avrohugger/overridesettings/build.sbt#L12
@danebert which format are you generating to? Maybe use
avroSpecificScalaSource. https://github.com/julianpeeters/sbt-avrohugger#settings
I am using the 'specific'
The error is that Unions beyond nullable fields are not supported
But shouldnt this just turn into an Option[String]?
like adding newlines in between the fields, etc...
