Desired timeslice in seconds5/5/2023 List of application ids to use for aggregating host level metrics for an application.Ä®xample: bytes_read across Yarn Nodemanagers. JDBC resultset prefect size for aggregator queries. Time in seconds to sleep on the first run or when the checkpoint is too old. Calculated as follows:Ĥ aggregate metrics/min * 60 * 24: Retrieve aggregate data for 1 day. Max result limit on number of rows returned. This can be changed only before creating tables. schemeĬompression codes need to be installed and available before setting the scheme.Äefault compression is SNAPPY. block.encodingĬodecs are enabled on a table by setting the DATA_BLOCK_ENCODING property.Äefault encoding is FAST_DIFF. Lowest resolution of desired data for cluster level minute aggregates. *.disabledÄisable host based * aggregations. Charles On Thu, at 9:22 AM Patrik Schindler < multipler * aggregation_interval. The recommended upper bound for timeslice in low-priority applications is 1.5 milliseconds (ms). The aggregators store the timestamp or last run time on local FS. Time in seconds to sleep for the day resolution cluster wide aggregator. Time in seconds to sleep for the hourly resolution cluster wide aggregator. Time in seconds to sleep for the minute resolution cluster wide aggregator. Time in seconds to sleep for the day resolution host based aggregator. Time in seconds to sleep for the hourly resolution host based aggregator. Time in seconds to sleep for the minute resolution host based aggregator. On wake up the aggregator threads resume from (last run time + interval) as long as last run time is not too old. Modifying the aggregation intervals for HOST and CLUSTER aggregators. Note: The precision table at 1 minute resolution stores raw precision data for 1 day, when user queries for past 1 hour of data, the AMS API returns raw precision data. daily.ttlĬluster wide daily resolution data purge interval. hourly.ttlĬluster wide hourly resolution data purge interval. minute.ttlĬluster wide minute resolution data purge interval. Host based daily resolution data purge interval. If an infinite time-slice quantum is desired the RWTHRPREEMPTIVE. returns a long result representing the number of elapsed seconds since. Host based hourly resolution data purge interval. The library converts milliseconds into seconds and nanoseconds so the value can be. The timeslicer increments the long variable named TIMESLICECOUNT each timeslice. (X = configurable interval, default interval is 2 minutes) Host based X minutes resolution data purge interval.
