New features

  • pl$read_ipc() can read a raw vector of Apache Arrow IPC file (#1072).
  • New method <DataFrame>$to_raw_ipc() to serialize a DataFrame to a raw vector of Apache Arrow IPC file format (#1072).
  • New method <LazyFrame>$serialize() to serialize a LazyFrame to a character vector of JSON representation (#1073).
  • New function pl$deserialize_lf() to deserialize a LazyFrame from a character vector of JSON representation (#1073).
  • New methods $str$head() and $str$tail() (#1074).
  • New S3 methods nanoarrow::as_nanoarrow_array_stream() and nanoarrow::infer_nanoarrow_schema() for RPolarsSeries (#1076).
  • New method $dt$is_leap_year() (#1077).
  • as_polars_df() and as_polars_series() supports arrow::RecordBatchReader (#1078).
  • The new experimental argument for as_polars_df(<ArrowTabular>), as_polars_df(<RecordBatchReader>), as_polars_series(<nanoarrow_array_stream>), and as_polars_df(<nanoarrow_array_stream>) (#1078).
    If experimental = TRUE, these functions switch to use the Arrow C stream interface internally.
    At this point, the performance is degraded under the expected use cases, so the default is set to experimental = FALSE.
