In fact, the testing done with Netfrastructure (aka Falcon) and NuoDB
showed that just
storing values with the encoding Jim described) reduced the overall record
size by 30%
compared with the run length encoding done by SQZ. The major gain with SQZ
is eliminating
trailing blanks and compressing a series of numeric columns with the value
zero.
So, it might be possible to make SQZ a lot dumber.
