com.amazonaws.services.glue.writeDynamicFrame 的 SparkQL 选项是什么?
What are the SparkQL options for com.amazonaws.services.glue.writeDynamicFrame?
它提到:"any options that are accepted by the underlying SparkSQL code can be passed to it by way of the connection_options map parameter."
但是,我怎样才能知道这些选项是什么? Glue 代码和 SparkQL 代码之间没有明确的映射。
(具体来说,我想弄清楚如何控制生成的 parquet 文件的大小)
