What data structure types cannot be ingested into a VARIANT column in a Snowflake table PARQUET XML RCFILE AVRO

Table of Contents

Correct Answer:

RCFILE

Analyzing the Answer：

Snowflake’s VARIANT data type is designed to be flexible and accommodate various semi-structured and structured data formats. However, it has limitations. While it can handle JSON, Avro, Parquet, and XML data, it cannot directly ingest RCFILE (Record Columnar File) format. RCFILE is an older Hadoop-based file format not directly supported by Snowflake’s data ingestion processes. Snowflake would require an intermediary step (like converting the RCFILE to another supported format) before loading it into a VARIANT column.

Analysis of other options：

A: PARQUET – Incorrect. Snowflake supports ingesting Parquet files directly into VARIANT columns.
B: XML – Incorrect. Snowflake supports ingesting XML data into VARIANT columns.
D: AVRO – Incorrect. Snowflake supports ingesting Avro files directly into VARIANT columns.
