From some initial experiments, I > think there is great potential to achieve compression rates around 30-50%. > Given those numbers, I think this is very low hanging fruit to implement. > One point to consider in the implementation is that compression blocks should > respect key-groups, i.e. typically it should make sense to compress per > key-group. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
