Code Examples

Polars

Casting is enums, categoricals etc is not essential, but may speed up parsing. Swapping int for pl.UInt16, pl.Int32 would also speed up parsing. However some of the datatypes are inferred, so they may be wrong.

This code deduplicates for you. Deduplication is normally only required across multiple months.

This code assumes that all columns are present, which may not be true for older files.

Availability

Visibility: Private & Public Next-Day

This table is in the public monthly MMSDM archive.

I have collated the list of all those files into one place, in this CSV metadata file. (Columns year, month, url, compressed_size in bytes).

The earliest available data is month 1 of 2015. The most recent available data is month 2 of 2021.

Warning

There are some months with no files.

Data Size

Each year of data is approximately 63 KB when zipped, 635 KB as unzipped CSV.

Deduplication and PDR Loader Configuration

The primary keys are:

The transaction type is "insert", which means that you will usually not see duplicate data. If you do, you can deduplicate based on the primary keys, without sorting first. Rows from different files with the same primary keys should have the same values.

PDR Loader configuration is:

Report Name Report Subtype Version Undisclosed
BID MNSP_OFFERTRK 1
OFFER MNSP_OFFERTRK 1 ⚠️

Warning

Some of these file mappings are not in the published PDR Loader configuration file, even though files for this table exist with those metadata values. Mappings marked with ⚠️ have been added by me after manually inspecting those files.

This means that the CSV files start with metadata columns:

I,BID,MNSP_OFFERTRK,1,...
D,BID,MNSP_OFFERTRK,1,...

or

I,OFFER,MNSP_OFFERTRK,1,...
D,OFFER,MNSP_OFFERTRK,1,...
