antirez	3f2d7e277e	Streams: items compression implemented. ... The approach used is to set a fixed header at the start of every listpack blob (that contains many entries). The header contains a "master" ID and fields, that are initially just obtained from the first entry inserted in the listpack, so that the first enty is always well compressed. Later every new entry is checked against these fields, and if it matches, the SAMEFIELD flag is set in the entry so that we know to just use the master entry flags. The IDs are always delta-encoded against the first entry. This approach avoids cascading effects in which entries are encoded depending on the previous entries, in order to avoid complexity and rewritings of the data when data is removed in the middle (which is a planned feature).	2017-12-01 10:24:24 +01:00
