CFPB Public Data API

This is the source project for the CFPB public data API at It contains up-to-date load scripts for populating data in that API. Note, however, that the resources/static/ directory is a work in progress; refer to for the current static resources.

Create a config file

cp sample_config.edn config.edn

Edit that file with appropriate values, including MongoDB connection information.

Loading data

To load the HMDA dataset, run lein repl and enter the following:

(-main "config.edn") ;; use the name of your config file. config.edn is an example
(require 'qu.loader)
(in-ns 'qu.loader)
(load-dataset "hmda")

Then close your REPL, using Ctrl-D. This does start the web server, so you may want to use a different configuration that starts it on an unpublished port.

Speeding up data load

You can take advantage of more CPU and Ram by concurrently loading chunks of data by splitting the large data file into smaller files with 1 million records each.

./ hmda_lar_all_2012.csv split_hmda_2012_

Then update the definition.json file to load these split files instead of the single CSV. Edit the hmda_lar sources section and replace it with a list of all the split files for the year you're targeting.

For example, for 2012, it looks like this:
