Expand description
StatisticsConverter to convert statistics in parquet format to arrow [ArrayRef].
Macros§
- get_
data_ 🔒page_ statistics - get_
statistics 🔒 - Special macro to combine the statistics iterators for min and max. This is used to avoid repeating the same code for min and max statistics extractions
- make_
decimal_ 🔒stats_ iterator - Special iterator adapter for extracting i128 values from from an iterator of
ParquetStatistics - make_
stats_ 🔒iterator - Define an adapter iterator for extracting statistics from an iterator of
ParquetStatistics
