+; List of replicator client authentication plugins to try. Plugins will be

|
|
|
+; would be used at the end of the list as a "catch-all". It doesn't do anything
|
|
|
+; and effectively implements the previous behavior of using basic auth.
|
|
|
+; There are currently two plugins available:
|
|
|
+; couch_replicator_auth_session - use _session cookie authentication
|
|
|
+; couch_replicator_auth_noop - use basic authentication (previous default)
|
|
|
+; Currently, the new _session cookie authentication is tried first, before

|
|

|
|
|
+
|

|
|
|
+; handle the case where anonymous writes are allowed to the database and a VDU
|
|
|
+; function is used to forbid writes based on the authenticated user name. In
|
|
|
+; that case this value should be adjusted based on the expected minimum session

|
|

+; checking whether databases and view indexes need compacting. The
|
|
|

|
|
|
+; List of compaction rules for the compaction daemon.
|
|
|
+; The daemon compacts databases and their respective view groups when all the
|
|
|
+; condition parameters are satisfied. Configuration can be per database or
|
|
|
+; global, and it has the following format:
|
|
|
+;
|
|
|
+; database_name = [ {ParamName, ParamValue}, {ParamName, ParamValue}, ... ]
|
|
|
+; _default = [ {ParamName, ParamValue}, {ParamName, ParamValue}, ... ]
|
|
|
+;
|
|
|
+; Possible parameters:
|
|
|
+;
|
|
|
+; * db_fragmentation - If the ratio (as an integer percentage), of the amount
|
|
|
+; of old data (and its supporting metadata) over the database
|
|
|
+; file size is equal to or greater then this value, this
|
|
|
+; database compaction condition is satisfied.
|
|
|
+; 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 database's information URI (GET /dbname/).
|
|
|
+;
|
|
|
+; * view_fragmentation - If the ratio (as an integer percentage), of the amount
|
|
|
+; of old data (and its supporting metadata) over the view
|
|
|
+; index (view group) file size is equal to or greater then
|
|
|
+; this value, then this view index compaction condition is
|
|
|
+; satisfied. 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. This estimation corresponds to 2 times the data size of
|
|
|
+; the database or view index. When there's not enough free disk space to compact
|
|
|
+; a particular database or view index, a warning message is logged.
|
|
|
+;
|
|
|
+; Examples:
|
|
|
+;
|
|
|
+; 1) [{db_fragmentation, "70%"}, {view_fragmentation, "60%"}]
|
|
|
+; The `foo` database is compacted if its fragmentation is 70% or more.
|
|
|
+; Any view index of this database is compacted only if its fragmentation
|
|
|
+; is 60% or more.
|
|
|
+;
|
|
|
+; 2) [{db_fragmentation, "70%"}, {view_fragmentation, "60%"}, {from, "00:00"}, {to, "04:00"}]
|
|
|
+; Similar to the preceding example but a compaction (database or view index)
|
|
|
+; is only triggered if the current time is between midnight and 4 AM.
|
|
|
+;
|
|
|
+; 3) [{db_fragmentation, "70%"}, {view_fragmentation, "60%"}, {from, "00:00"}, {to, "04:00"}, {strict_window, true}]
|
|
|
+; Similar to the preceding example - a compaction (database or view index)
|
|
|
+; is only triggered if the current time is between midnight and 4 AM. 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}]
