Which data formats offers the most efficient storage and performance?

Compared to a traditional approach where data is stored in a row-oriented approach, Parquet file format is more efficient in terms of storage and performance. It is especially good for queries that read particular columns from a “wide” (with many columns) table since only needed columns are read, and IO is minimized.

How do you organize large datasets?

Here are 11 tips for making the most of your large data sets.

  1. Cherish your data. “Keep your raw data raw: don’t manipulate it without having a copy,” says Teal.
  2. Visualize the information.
  3. Show your workflow.
  4. Use version control.
  5. Record metadata.
  6. Automate, automate, automate.

Which file storage format has the highest performance?

If query performance is most important, then ORC or Parquet are optimal, but these files take longer to write. If the schema is going to change over time, then Avro is best, but query performance will be slower than ORC or Parquet. CSV files are best if extract data from Hadoop to bulk load into a database.

Which file format is best suited for archival purpose?

TIFF (Tagged Image File Format) is universally considered a good format for archiving photo collections.
