No, not really.

The blog post talks about storing JSON data in a column-oriented database.

The blog post talks about importing data from JSON docs into their database. Prior to this, they stored JSON documents in their database like any standard off-the-shelf database does. Now they parse the JSON document when importing, and they store those values in their column-oriented database as key-value pairs, and preserve type information.

The silly part is that this all sounds like a intern project who was tasked with adding support to import data stored in JSON files into a column-oriented database, and an exporter along with it. But no, it seems an ETL job now counts as inventing JSON.
