FileStats

delta_kernel::crc

Struct FileStats 

Source 
pub struct FileStats { /* private fields */ }
Available on crate feature internal-api only.
Expand description

File-level statistics for a table version: total file count, size, and histogram.

Obtained via Snapshot::get_file_stats_if_present or Crc::file_stats(). Returns None when the source CRC’s file_stats_state is not Complete.

Implementations§

Source§

impl FileStats

Source

pub fn num_files(&self) -> i64

Returns the number of active Add file actions in this table version.

Source

pub fn table_size_bytes(&self) -> i64

Returns the total size of the table in bytes (sum of all active Add file sizes).

Source

pub fn file_size_histogram(&self) -> Option<&FileSizeHistogram>

Returns the size distribution of active files, if available.
