17.7 Compression format of input data files
This section explains the compression format of input data files.
The adbimport command can even import input data files (CSV or fixed-length format) that are in the following compression format.
- ▪ Compression format of input data files
-
-
GZIP format
-
The following GZIP-format compressed files can be imported by using the adbimport command:
-
Input data files (CSV or fixed-length format) compressed in GZIP format by using the OS gzip command
-
Output data files (CSV format) compressed in GZIP format by using the adbexport command with the --compress GZIP option specified
For details about the compression format of output data files, see 14.6 Compression format of output data files.
Compressed input data files are imported by using the same method as for uncompressed input data files. Data can be imported by executing the adbimport command in which the absolute path to the storage location of the compressed input data file is specified for the input data path file.
- Important
-
Only GZIP can be used as the compression format of input data files. Input data files compressed in other formats cannot be imported.
When importing input data files compressed in formats other than GZIP format, decompress the compressed input data files before importing them.
