We provide you with an Oracle sample database named OT which is based on a global fictitious company that sells computer hardware including storage, motherboard, RAM, video card, and CPU.

The company maintains the product information such as name, description standard cost, list price, and product line. It also tracks the inventory information for all products including warehouses where products are available.

Because the company operates globally, it has warehouses in various locations around the world. The company records all customer information including name, address, and website. Each customer has at least one contact person with detailed information including name, email, and phone. The company also places a credit limit on each customer to limit the amount that customer can owe.

Whenever a customer issues a purchase order, a sales order is created in the database with the pending status. When the company ships the order, the order status becomes shipped. In case the customer cancels an order, the order status becomes canceled. In addition to the sales information, the employee data is recorded with some basic information such as name, email, phone, job title, manager, and hire date. Download Oracle Sample Database.

With a million-row table, every byte in each row represents a megabyte of total data volume. This particular record takes up 78 characters, including the comma separators. This query considers every row in the table, so there are no shortcuts to avoid reading all 78 megabytes. Is 78 MB a lot of data to process with Hadoop on a parallel cluster of computers?

That fact is significant because when breaking down the work to execute SQL queries in parallel on Hadoop, the smallest unit of measure is the block. If you have a 5-node cluster, how many nodes are needed to process 78 MB? Just one. How about if you have a node cluster? Of course, you can split up the original data into more than one file. But keep in mind that a Hadoop cluster with fast disk drives can read a MB block in the blink of an eye.

The overhead to send requests back and forth on the network roughly balances out the performance benefit from doing such a small query in parallel across multiple nodes.

Spoiler: it looks even less substantial when you start applying other best practices such as binary file formats and partitioning. In practice, you would store your data in an efficient binary format such as Parquet, instead of as a bulky text file with millions of commas and requiring six bytes to encode a six-figure salary.

In Parquet, the numbers are compacted in binary format, repeated values are encoded to minimize repetition, columns with a modest number of different values are encoded using numeric IDs, and the result is compressed one final time at the end.

The original 78 MB of text might be packed down to MB, or even less.
