optimizing compression (no replies)

Hi,

I'm currently in the process of compressing a rather big database and there are 2 tables which last pretty long.

One is of size in FS:
# ls -lh *campa_placementidlist1*
-rw-rw---- 1 mysql mysql 8.5K Sep 11 11:54 campa_placementidlist1.frm
-rw-rw---- 1 mysql mysql 288G Sep 24 12:05 campa_placementidlist1.ibd

It currently runs since over 47 hours although we have a pretty strong server:
Mem: 148267056k with 24 cores
# innodb parameters
innodb_data_home_dir=/mysqldb/data
innodb_file_per_table
innodb_file_format=BARRACUDA
innodb_data_file_path = ibdata1:100M:autoextend
innodb_buffer_pool_size=112640M
# innodb_buffer_pool_instances=8
innodb_log_file_size=1024M
innodb_log_buffer_size=10M
innodb_thread_concurrency=16

I also can't find any temporary table on disk, so I assume it's handled completely in the cache.
That's why I'm thinkinf of defining a high temp_table_size of 8GB or more.
But I first want to let it complete. There is one gt 900 GB table left to compress ...

Is there a way to improve this? Any timps or comments on this are welcome.

Best Regards,
Jens
