[jira] [Resolved] (AVRO-3050) Request for Documentation for Fixed
Decimal Type in JSON data representation
[ https://issues.apache.org/jira/browse/AVRO-3050?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Divya resolved AVRO-3050.
-------------------------
Resolution: Information Provided
> Request for Documentation for Fixed Decimal Type in JSON data representation
> ----------------------------------------------------------------------------
>
> Key: AVRO-3050
> URL: https://issues.apache.org/jira/browse/AVRO-3050
> Project: Apache Avro
> Issue Type: Task
> Components: java, logical types
> Affects Versions: 1.8.0
> Reporter: Divya
> Priority: Major
>
> We are trying to use a fixed type for logicalType Decimal. We create JSON and then convert it into Parquet(Avro). There, we are trying to call conversion.toFixed(), but it is returning in bytes (Array.toString(bytes)). We are using Avro 1.8 version.
>
> BigDecimal d1 = new BigDecimal("124.56")
> LogicalType decimal = LogicalTypes.decimal(9, 2);
> Schema fixedSchema = Schema.createFixed(Schema.Type.FIXED.name, null, null, 16);
> Conversion<BigDecimal> conversion = new Conversions.DecimalConversion();
> GenericFixed d1fixed = conversion.toFixed(d1, fixedSchema, decimal);
>
>
> Is there any method that we can use to convert it into 'Fixed text' that JSONDecoder is expecting? Any help will be appreciated.
