The `[api]/instance_list_per_project_cells` configuration option
|
|
was added, which controls whether or not an instance list for
|
|
non-admin users checks all cell databases for results. If
|
|
disabled (the default), then a list will always contact each cell
|
|
database looking for instances. This is appropriate if you have a
|
|
small number of cells, and/or if you spread instances from tenants
|
|
evenly across cells. If you confine tenants to a subset of cells,
|
|
then enabling this will result in fewer cell database calls, as
|
|
nova will only query the cells for which the tenant has instances
|
|
mapped. Doing this requires one more (fast) call to the API
|
|
database to get the relevant subset of cells, so if that is likely
|
|
to always be the same, disabling this feature will provide better
|
|
performance.
