Merge remote branch 'cloudant:3102-fix-return-value' This closes #16 Signed-off-by: ILYA Khlopotov <iilyak@ca.ibm.com>
This app supplies the functionality for the /_db_updates
endpoint.
When a database is created, deleted, or updated, a corresponding event will be persisted to disk (Note: This was designed without the guarantee that a DB event will be persisted or ever occur in the _db_updates
feed. It probably will, but it isn't guaranteed). Users can subscribe to a _changes
-like feed of these database events by querying the _db_updates
endpoint.
When an admin user queries the /_db_updates
endpoint, they will see the account name associated with the DB update as well as update
1: global_changes
, db_writes
: The number of doc updates caused by global_changes.
2: global_changes
, server_pending_updates
: The number of documents aggregated into the pending write batch.
3: global_changes
, listener_pending_updates
: The number of documents aggregated into the pending event batch.
4: global_changes
, event_doc_conflict
: The number of rev tree branches in event docs encountered by global_changes. Should never happen.
5: global_changes
, rpcs
: The number of non-fabric RPCs caused by global_changes.
1: global_changes
, max_event_delay
: (integer, milliseconds) The total timed added before an event is forwarded to the writer.
2: global_changes
, max_write_delay
: (integer, milliseconds) The time added before an event is sent to disk.
3: global_changes
, update_db
: (true/false) A flag setting whether to update the global_changes database. If false, changes will be lost and there will be no performance impact of global_changes on the cluster.
