PMS_GROUP
Entity table for group
Column Schema
GROUPID
Abstract identifier for the group
SQL Type: NUMBER(20,0)
Polars Type: pl.Int128
This column is mandatory, and a primary key.
Examples:
3, 283
CREATEDDATE
Date record was created
SQL Type: TIMESTAMP(3)
Polars Type: pl.Datetime()
This column is not mandatory.
Example: 2021/09/21 13:38:51.717
Unlike most datetime columns, this one includes a millisecond component.
e.g. 2029/03/15 00:00:00.123.
LASTCHANGED
Date record was last changed
For more information, see the dedicated documentation page.
SQL Type: TIMESTAMP(3)
Polars Type: pl.Datetime()
This column is not mandatory.
Example: 2021/09/21 13:38:51.717
Unlike most datetime columns, this one includes a millisecond component.
e.g. 2029/03/15 00:00:00.123.
New Data Timing
When the record is created or updated
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.

# Note that Polars uses slightly different format strings for fractional seconds to `dt.strptime`
# e.g. "2029/03/15 00:00:00.123".

# Deduplicate
# We want one row per ['GROUPID']
# Tie-breaker: greatest value of LASTCHANGED
.sort(LASTCHANGED, descending=False)
.unique(subset=["GROUPID"], keep="last")

Availability
Visibility: Public
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 8 of 2024. The most recent available data is month 9 of 2026.
Every month in between has a file. (No gaps.)
Data Size
Each year of data is approximately 54 KB when zipped, 543 KB as unzipped CSV.
Deduplication and PDR Loader Configuration
The primary keys are:
The transaction type is "UPDATE-INSERT", which means that you will likely see duplicate data with different values.
You should deduplicate by sorting based on LASTCHANGED, within each group of primary keys.
| Report Name | Report Subtype | Version |
|---|---|---|
| PARTICIPANT_REGISTRATION | PMS_GROUP | 1 |
This means that the CSV files start with metadata columns:
ROW_FILTER_TYPE is LASTCHANGED
