Add
cpu_percent_normalized
to themz_internal.mz_{source,sink,cluster_replica}_utilization
system catalog views. This column provides an approximation of CPU utilization as a % of the total of compute workers. -
Add
mz_internal.mz_cluster_replica_frontiers
to the system catalog. This table describes the frontiers of each dataflow in the system. -
Private preview. Support the
AS OF
andUP TO
clauses inSUBSCRIBE
. These clauses allow specifying a timestamp at whichSUBSCRIBE
should begin returning results (AS OF
), or cease running (UP TO
).As is, all user-defined sources and tables have a retention window of one second, so
AS OF
is of limited use beyond subscribing to queries over specific system catalog objects (includingmz_cluster_replicas
,mz_sources
,mz_sinks
,mz_internal.mz_cluster_replica_metrics
, andmz_internal.mz_cluster_replica_sizes
).
