An amazing data prep tool that handles huge datasets with ease.
Datameer is awesome. Not cheap. But for the right jobs, it's totally worth it. After Excel and other ETL tools kept crashing on us when prepping 10-100+ million line csv files for loading into DynamoDB and Aurora RDS, Datameer saved us by effortlessly handling deduping and adding columns to huge files while giving us an Excel-like spreadsheet interface that makes it pretty easy to figure out. It also does a great job letting you filter out bad data during import and applying regex, logic formulas, and joining and combining multiple files together. We've used it to prep a couple billion rows worth of text files for import into databases without any big problems. Highly recommended.
