Welcome Vivianna, I think taking a look at https://issues.apache.org/jira/browse/PARQUET-41 and sub-issues should give you a sense of the current implementation. Java seems to have an implementation.
The python implementation of parquet is a binding on top of the C++ implementation. Bloom filters haven't been implemented in C++ to my knowledge. Hope this helps. -Micah On Mon, Jan 25, 2021 at 9:05 AM Viviana Elizabeth Romero Noguera < viviana.nogu...@usp.br> wrote: > Hi. > I am a doctoral student at ICMC - USP in Brazil. > I am looking to work with apache parquet.
