java - Decimal datatype support in avro schema and generated files -


avro version 1.8.1.

we have below field in avro schema

"name" : "sale_price", "type" : ["bytes", "null"], "logicaltype": "decimal", "precision": 18, "scale": 17,

we have defined logicaltype decimal.

but when use avro-maven-plugin, not generate correct data type generated java files.

<plugin>     <groupid>org.apache.avro</groupid>     <artifactid>avro-maven-plugin</artifactid>     <version>1.8.1</version>     <configuration>         <stringtype>string</stringtype>         <enabledecimallogicaltype>true</enabledecimallogicaltype>     </configuration> </plugin>

currently generates, java.nio.bytebuffer. how have correct data type generated java files.

as avro docs explain,

language implementations must ignore unknown logical types when reading, , should use underlying avro type.

a decimal logical type annotates avro bytes or fixed types.

hence in generated java files, decimal logical type represented in underlying avro type bytes, i.e., java.nio.bytebuffer
