Fields

file_path: Option<String>

File where column data is stored. If not set, assumed to be same file as metadata. This path is relative to the current file.

file_offset: i64

Byte offset in file_path to the ColumnMetaData *

meta_data: Option<ColumnMetaData>

Column metadata for this chunk. This is the same content as what is at file_path/file_offset. Having it here has it replicated in the file metadata.

offset_index_offset: Option<i64>

File offset of ColumnChunk’s OffsetIndex *

offset_index_length: Option<i32>

Size of ColumnChunk’s OffsetIndex, in bytes *

column_index_offset: Option<i64>

File offset of ColumnChunk’s ColumnIndex *

column_index_length: Option<i32>

Size of ColumnChunk’s ColumnIndex, in bytes *

crypto_metadata: Option<ColumnCryptoMetaData>

Crypto metadata of encrypted columns *

encrypted_column_metadata: Option<Vec<u8>>

Encrypted column metadata for this chunk *
