box.read_view.list()

read_view.list()¶

Return an array of all active database read views. This array might include the following read view types:

• read views created by application code (Enterprise Edition only)
• system read views (used, for example, to make a checkpoint or join a new replica)

Read views created by application code also have the space field. The field lists all spaces available in a read view, and may be used like a read view object returned by box.read_view.open().

Примечание

read_view.list() also contains read views created using the C API (box_raw_read_view_new()). Note that you cannot access database spaces included in such views from Lua.

Example:

tarantool> box.read_view.list()
