WebDatasets can be created from Hadoop InputFormats (such as HDFS files) or by transforming other Datasets. Due to Python’s dynamic nature, we don’t need the Dataset to be strongly-typed in Python. As a result, all Datasets in Python are Dataset[Row], and we call it DataFrame to be consistent with the data frame concept in Pandas and R.

caching - What do the TensorFlow Dataset

WebFeb 7, 2024 · Caching data into memory by properly setting the storage mode can boost the query performance and interactivity of your reports. Large datasets: Tables that aren't cached don't consume memory for caching purposes. You can enable interactive analysis over large datasets that are too large or expensive to completely cache into memory. WebChunk Caching Another major feature of the dataset chunking scheme is the chunk cache. As it sounds, this is a cache of the chunks in the dataset. This cache can greatly improve performance whenever the same chunks are read from or written to multiple times, by preventing the library from having to read from and write to disk multiple times.
