We only support comma(‘,’), semicolon(‘;’), vertical bar(‘|’) and tab(‘\t’) as delimiter. Rows that have different number of columns than the header row will be judged as error rows. (numbers of error rows / numbers of rows sampled ) must be less than 0.1.
  > * For Parquet files, if you are using a self-hosted integration runtime, you need to install the **64-bit JRE 8 (Java Runtime Environment) or OpenJDK** on your IR machine. Check our [Java Runtime Environment section at the bottom of the page](manage-integration-runtimes.md#java-runtime-environment-installation) for an installation guide.
