Sifang Li created ARROW-15790:
---------------------------------
Summary: field's metadata is not write into Parquet file
Key: ARROW-15790
URL: https://issues.apache.org/jira/browse/ARROW-15790
Project: Apache Arrow
Issue Type: Bug
Environment: Ubuntu
Reporter: Sifang Li
I used this code to test the metadata write into file and read back behavior of
parquet file:
[https://gist.github.com/dantrim/33f9f14d0b2d3ec45c022aa05f7a45ee]
The generated file does not have metadata when I read the file in using code
below and print it out:
{quote}std::shared_ptr<arrow::io::ReadableFile> infile;
PARQUET_ASSIGN_OR_THROW(infile,
arrow::io::ReadableFile::Open("./test.parquet", arrow::default_memory_pool()));
std::unique_ptr<parquet::arrow::FileReader> reader;
PARQUET_THROW_NOT_OK(
parquet::arrow::OpenFile(infile, arrow::default_memory_pool(), &reader));
std::shared_ptr<arrow::Table> table;
PARQUET_THROW_NOT_OK(reader->ReadTable(&table));
EXPECT_EQ(frameCount, table->num_rows());
std::cout<<"==="<<table->schema()->ToString(true) <<std::endl; /// no meta
shown{quote}
