如何确保镶木地板文件包含元数据中的行数？
How ensure that parquet files contains row count in metadata?
查看来源：fast-parquet-row-count-in-spark and parquet-count-metadata-explanation
Whosebug 和官方 spark 文档告诉我们 parquet 文件应该在元数据中包含 row count。自 1.6
以来，spark 默认添加了这个
我试图看到这个“领域”，但没有成功。可能是我做错了什么？有人能告诉我如何确保某些镶木地板文件有这样的文件吗？欢迎任何 link 到小而好的镶木地板文件！现在我用参数 meta D:\myparquet_file.parquet 调用 org.apache.parquet.tools.Main 并且在结果中看不到 count 关键字。
您可以使用 parquet-tools:
检查镶木地板文件
- 安装
parquet-tools:
pip install parquet-tools
- 创建镶木地板文件。我使用 spark 创建了一个包含 3 行的小型镶木地板文件：
import spark.implicits._
val df: DataFrame = Seq((1, 2, 3), (4, 5, 6), (7, 8, 9)).toDF("col1", "col2", "col3")
df.coalesce(1).write.parquet("data/")
- 检查镶木地板文件：
parquet-tools inspect /path/to/parquet/file
输出应该是这样的：
############ file meta data ############

您可以在 file meta data 部分下看到表示镶木地板文件中行数的 num_rows 字段。
您可以在行组旁边的 RC 字段中找到行数。
