Apache Parquet is a columnar file format to
work with gigabytes of data. Reading and writing parquet files is efficiently
exposed to python with pyarrow. Additional statistics allow clients to use
predicate pushdown to only read subsets of data to reduce I/O.
Organizing data by column allows for better
compression, as data is more homogeneous. Better compression also reduces the
bandwidth required to read the input. |
