HappyBase - Is there an equivalent of find_one or scan_one?

All the rows in a particular HBase table that I am making a UI for happen to have the same columns and will have so for the foreseeable future. I would like my html data visualizer application to simply query for a single random row to take note of the column names, and put this list of column names into a variable to refer to throughout the program.

I didn't see any equivalent to find_one or scan_one in the docs for HappyBase.

What is the best way to accomplish this?

Solution

  • This will fetch only the first row:

    row = next(table.scan(limit=1))

    Additionally you can specify a filter string to avoid retrieving the values, which is only worthwile if your values are large and you're performing this query often.
