# Data File Cataloguer Connect your Data File Cataloguer to Aiimi Insight Engine to make the most of the data. 1. **Source System:** Select Data File Cataloguer from the dropdown. ## **Initial Configuration Steps** 1. **Sources:** Enter the sources the should be crawled for data files. 2. **Sample Rows:** Enter the number of rows that should be run as a test. * This is the number of sample rows that will be extracted from each data file. 3. **Download folder:** Enter the folder path that will store download files as they are being catalogued. * This location must be accessible by the machine running the crawl. * If left blank or NULL the system temp folder will be used. *** ## Additional Settings 1. **Attempt direct access:** If checked this improves performance of files on a file share. * If direct access fails or cannot be used the file will be downloaded locally. 2. **Limit deltas to new or deleted file only:** If checked only new or deleted files will processed. Modified files will not update. * This improves performance but the accuracy of content can suffer. 3. **Multipart parquet support:** If checked it will process groups of parquet files in a folder as one file with multiple parts. * Each part must be name "part-(#)-tid-(guide)-(name).parquet" for this to work. 4. **Approximate multipart parquet row count:** * If checked it will count the first part of a multipart parquet and multiply that by the number of parts.
