ALTER SYSTEM¶
Synopsis¶
1 | |
Description¶
Sets and modifies the value of system-level configs. These
are properties that are applied to all queries in the cluster.
Using ALTER SYSTEM results in the new value being applied
immediately across the cluster and restarts the shared runtime
to take effect for existing queries.
To use the ALTER SYSTEM statement, the ksql.runtime.feature.shared.enabled
configuration setting must be true.
ALTER SYSTEM is available only from the ksql command line and only when
connected to a ksqlDB cluster in Confluent Cloud.
Example¶
The following statement sets the streams property auto.offset.reset to begin at the
earliest record in the input topics when no committed offsets are found.
