Use term_to_binary with minor_version=1 to reduce disk size of data and indexes
-------------------------------------------------------------------------------
Key: COUCHDB-1382
URL: https://issues.apache.org/jira/browse/COUCHDB-1382
Project: CouchDB
Issue Type: Improvement
Components: Database Core
Affects Versions: 1.1.1
Environment: doesn't matter
Reporter: Alexey Loshkarev
Priority: Trivial
Now, couchdb store data using term_to_binary/1 (with no options).
According manual, term_to_binary/2 has option minor_version, which value 1
changes storage format for floats.
Default behaviour, float consume 33 bytes of disk space.
With minor_version=1, float consume only 9 bytes of disk space.
minor_version=1 is supported since Erlance 11B-4, but minimum couchdb supported
erlang version is still 13, so no problem to implement this.
Also, term_to_binary/2 has "compressed" option, it may also reduce disk space,
but will use more cpu for that.
