…he#41506) ## Proposed changes Reason: https://issues.apache.org/jira/browse/ARROW-5322 Java readers(parquet-mr) handles "dictionaryPageOffset = 0" to determine if dictionary page exists where as the C readers uses "has_dictionaryPageOffset" (_isset bit in thrift message) to determine the same resulting in incompatible behaviours. Therefore, we should consider that dicttionary page exists when both `__isset.dictionary_page_offset` is true and `dictionary_page_offset` is greater than 0.
## Proposed changes Implemented reading parqeut files with decimal256 type
…der (apache#41683) ## Proposed changes Impl ByteStreamSplitDecoder to decode BYTE_STREAM_SPLIT encoding parquet. relate pr: apache/arrow#42372 > Apache Parquet does not have any encodings suitable for FP data and the available text compressors (zstd, gzip, etc) do not handle FP data very well. It is possible to apply a simple data transformation named "stream splitting". Such could be "byte stream splitting" which creates K streams of length N where K is the number of bytes in the data type (4 for floats, 8 for doubles) and N is the number of elements in the sequence. --------- Co-authored-by: morningman <morningman@163.com>
