To close out 2024, today's featured chart presents an estimate of the amount of new data added during 2024 and stored within the IEM PostgreSQL databases. Note that the numbers presented are not exactly point in time observations, but a measure of the number of database rows within various tables/relations. Please also note that the plot uses a logarithmic axis for readability. A small army of computer servers attempt to process numerous data streams into forms to be stored within a database. The featured chart totals an estimate of just under five billion rows of data added for the year! Most all of this data is made immediately available for download via numerous APIs and services. It is a considerable challenge to keep all of these data flows going, but the community feedback remains very positive with many usage cases at Iowa State University and beyond supported by this effort. Here's to another year of keeping the IEM chunking along!
