## Description The number of sequences that can be managed under this configuration has an upper limit, beyond which the performance and stability of the system cannot be guaranteed. To prevent the number of sequences managed by the system from exceeding the upper limit, metadata quota management is required to limit the number of sequences and devices managed by a cluster. cherry-pick from #9430 #9576 #9563 #9626 ## Docs * cluster_schema_limit_level: ``` # There are two available levels: 'device' and 'timeseries'. # 'device': The limit is applied to the number of devices in the cluster. # 'timeseries': The limit is applied to the number of timeseries in the cluster. cluster_schema_limit_level=timeseries ``` * cluster_schema_limit_threshold: ``` # This configuration parameter sets the maximum number of schema allowed in the cluster. # The value should be a positive integer representing the desired threshold. # When the threshold is reached, users will be prohibited from creating new time series. # -1 means unlimited cluster_schema_limit_threshold=-1 ``` Hot loading can be done via load configuration after all DataNode's `iotdb-common.properties` have been modified. ## ScreenShot <img width="1179" alt="image" src="https://github.com/apache/iotdb/assets/43774645/a74f1726-c02f-4be8-bcf0-4bb712256e0e";> -- This is an automated message from the Apache Git Service.
