CowRewriteResult

iceberg::cow_rewrite

Struct CowRewriteResult 

Source 
pub struct CowRewriteResult {
    pub removed_data_files: Vec<DataFile>,
    pub added_data_files: Vec<DataFile>,
    pub unchanged_data_files: Vec<DataFile>,
    pub stats: CowRewriteStats,
}
Expand description

Result of a copy-on-write rewrite operation.

Fields§

§removed_data_files: Vec<DataFile>

Old data files that should be removed by the commit action.

§added_data_files: Vec<DataFile>

New data files that should be added by the commit action.

§unchanged_data_files: Vec<DataFile>

Candidate files that were read and left unchanged.

Files whose visible rows were all removed by delete files are NOT included here: they read as zero rows and are reported in removed_data_files with no replacement. A commit adapter may remove position deletes and deletion vectors that exclusively reference these removed files, but must retain equality deletes that can still apply to other live files.

§stats: CowRewriteStats

Rewrite counters.
