Effective Queries with Rails and PostgreSQL
Your first impression may be that it's better to add indexes to every field in a database. However, first of all, only one of the defined indexes is working here (see the compound index section). Furthermore, indexes can slow down queries if there are not many records in the database, and each index takes up space in a computer's memory. Often, the size of the indexes may be larger than the amount of the data stored in a database. You can install the "rails-pg-extras" gem to get more information. I recommend that you carefully study the documentation of this gem, as it contains many useful functions that will make your work with the database as efficient as possible.

A better CSV import
In the first step, we only validate if the information is all there and correctly formatted. For example, if a location name is missing, we highlight that error in the spreadsheet. If everything looks good, we save the locations to the database using the awesome Activerecord-Import library, but skip calling the geocoding API. Rather, we mark these locations as "to be geocoded".
