- 2 Prelude: the most important question
- 3 TIME FOR A BIG DATA CLUSTER!!!!
- 4 A non-solution: don't use RAM, just disk
- 5 The software solution: use less RAM
- 6 Compression: Numpy dtypes
- 7 Compression: sparse arrays
- 8 Compression: Pandas dtypes When loading data you can specify types
- 9 Chunking: loading Numpy chunks with Zarr
- 10 Chunking: with Pandas
- 11 Indexing: the simplest solution
- 12 Indexing: Pandas without indexing
