As an option, you can compress data files when sending them to
Audience Manager supports gzip (.gz) compression for
inbound, asynchronous data transfers.
Audience Manager also supports uncompressed files.
We currently don't support encryption and
compression on the same inbound data file. You can select to either
or compress your inbound files.
Amazon S3 Compression
For delivery to Amazon S3, you must use
.gz or uncompressed files. Compressed files must be 1 GB
or smaller. If the files are larger, please discuss the file and transfer
process with Customer Care. Although
Audience Manager can handle very large files, there
may be ways to reduce the file size or make transfer of data more efficient.
Important: Your FTP client must use binary mode to transfer
compressed or encrypted files. Compressed or encrypted files sent in ASCII mode
will corrupt the data transfer file.
- Files should be gzip
compressed (and have a
.gz file extension.)
- The maximum compressed file
size for a
.gz compressed file is 1 GB.
- Optimal split sizes, for
fastest/earliest processing of your files, is approximately 1 GB uncompressed
or 200-300 MB compressed.
- Amazon S3 imposes its own, 5
GB file size limit on uploaded files.
