Acquire a session lock.
Submit edits to time series topic events which have an author which is the same as the principal of the calling session.
This permission is a more restrictive alternative to `EDIT_TIME_SERIES_EVENTS`.
The `UPDATE_TOPIC` permission is required to update a time series topic. This permission is additionally required to submit edits to a time series topic where the event author is the same as the principal of the calling session.
Expose a branch of the topic tree as a virtual session tree.
The EXPOSE_BRANCH path permission is powerful since it allows a
session to expose a whole branch of the topic tree under a different set
of path permissions.
A session granted EXPOSE_BRANCH for a particular path effectively
has the permission for all descendant paths. From a security perspective,
if a role grants EXPOSE_BRANCH at branch X it is
ineffectual for it also to deny EXPOSE_BRANCH at a child branch
X/Y because a branch mapping to X can still expose paths
below X/Y.
Add or remove topics
Evaluate queries that return a non-current view of a time series topic.
The `READ_TOPIC` permission is required to evaluate any type of `Query` for a time series topic. This permission is additionally required for queries that potentially return a non-current view of all or part of a time series. Such queries include value range queries that specify an edit range, and all types of edit range query.
Required to receive information from a topic.
If a session does not have read_path permission for a topic, the topic will be excluded from the results of subscription or fetch operations for the session, and the topic's details cannot be retrieved by the session.
Use a topic selector that selects the topic path
A session must have this permission for the path prefix of any topic selector used to subscribe or fetch.
When the subscription or fetch request completes, the resulting topics
are further filtered based on the READ_TOPIC permission.
A session that has READ_TOPIC but not
SELECT_TOPIC for a particular topic path cannot
subscribe directly to topics belonging to the path. However, the session can
be independently subscribed by a control session that has the
MODIFY_SESSION global permission in addition to the
appropriate SELECT_TOPIC permission.
A session granted SELECT_TOPIC for a particular path effectively
has the permission for all descendant paths. From a security perspective,
if a role grants SELECT_TOPIC at branch X it is
ineffectual for it also to deny SELECT_TOPIC at a child branch
X/Y because a a topic selector with a path prefix of X
can still select paths below X/Y.
