solr - 如何使用 Morphlines conf 文件读取 DECIMAL(38,10)

Question

我想使用 Morphlines 读取镶木地板文件。参考：https ://medium.com/@bkvarda/index-parquet-with-morphlines-and-solr-20671cd93a41

此 Parquet 文件具有 DECIMAL 数据类型。我没有找到任何文档，如何在 Morphlines 中处理 DECIMAL。我在 conf 文件中使用以下代码，但它不起作用。=============================test_morphlines.conf=================== =========== 命令：[

 # Read the Parquet data  

{ readAvroParquetFile {
    projection:
      readerSchemaString:"""{ "type": "record"
         ,"name": "my_record"
         ,"fields": [

{"name": "audit_internal_id","type":["bytes","null"],"logicalType":"decimal","precision":38,"scale":10,"default":0 }

,{"name": "alert_id","type":["bytes","null"],"logicalType":"decimal","precision":38,"scale":10,"default":0 } ]
}"""

    }
  }
