This value is computed as: ; ; (file_size - data_size) / file_size * 100 ; ; The data_size and file_size values can be obtained when ; querying a view group's information URI ; (GET /dbname/_design/groupname/_info). ; ; * from _and_ to - The period for which a database (and its view groups) compaction ; is allowed. The value for these parameters must obey the format: ; ; HH:MM - HH:MM (HH in [0..23], MM in [0..59]) ; ; * strict_window - If a compaction is still running after the end of the allowed ; period, it will be canceled if this parameter is set to 'true'. ; It defaults to 'false' and it's meaningful only if the *period* ; parameter is also specified. ; ; * parallel_view_compaction - If set to 'true', the database and its views are ; compacted in parallel. This is only useful on ; certain setups, like for example when the database ; and view index directories point to different ; disks. It defaults to 'false'. ; ; Before a compaction is triggered, an estimation of how much free disk space is ; needed is computed.

If at ; 4 AM the database or one of its views is still compacting, the compaction ; process will be canceled. ; ; 4) [{db_fragmentation, "70%"}, {view_fragmentation, "60%"}, {from, "00:00"}, {to, "04:00"}, {strict_window, true}, {parallel_view_compaction, true}] ; Similar to the preceding example, but a database and its views can be ; compacted in parallel. ; ;_default = [{db_fragmentation, "70%"}, {view_fragmentation, "60%"}, {from, "23:00"}, {to, "04:00"}]
