## CS 591 K1: Data Stream Processing and Analytics Spring 2020 ## 4 /09: Flow control and load shedding Vasiliki (Vasia) Kalavri vkalavri@bu.edu ## Keeping up with the producers • Producers can generate producer (back-pressure, flow control) ## Load management approaches  (a) Load shedding ![Image](/uploads/documents/1/8 transient load increase. ## Scale resource allocation: • Addresses the case of increased load and additionally ensures no resources are left idle when the input load decreases. ## Load shedding • Load shedding

WITH LABEL label [ (column [, ...]) ] { VALUES ( { expression | DEFAULT } [, ...] ) [, ...] | query } • table name 需要导入数据的表名。 • PARTITION 指定需要导入数据的分区。 • WITH LABEL 为本次 INSERT 操作指定一个 Label。如果不指定，则系统会自动生成一个随机 INTO tbl1 WITH LABEL label1 WITH cte1 AS (SELECT * FROM tbl1), cte2 AS (SELECT * FROM tbl2) SELECT k1 FROM cte1 JOIN cte2 WHERE cte1.k1 = 1; ### 4. 向 test 表中导入一个查询语句结果，并指定 partition 和 label INSERT INTO INTO test PARTITION(p1, p2) WITH LABEL `label1` SELECT * FROM test2; INSERT INTO test WITH LABEL `label1` (c1, c2) SELECT * FROM test2; ## Keywords INSERT ## 最佳实践 ### 1. 查看返回结果 INSERT 操作是一个同步操作，返回结果即

-> workers) • Bins are selected uniformly at random - At the end of the process, the maximum load is $\Theta(\ln n/\ln \ln n)$, with high probability • Instead, we select d destination bins, each ball at the least full bin: • when d=2, the maximum load is $ \ln \ln n / \ln 2 + O(\tau) $ , with high probability • when d>2, the maximum load keeps decreasing, but only by a constant factor ## Dynamic Dynamic resource allocation • Choose one among n workers • check the load of each worker and send the item to the least loaded one • load checking for every item can be expensive • Choose two workers at

is the focus of this chapter. We start this chapter with an introduction to sample efficiency and label efficiency, the two criteria that we have picked to benchmark learning techniques. It is followed the two prominent ways to benchmark the model in the training phase namely sample efficiency and label efficiency. ## Sample Efficiency Sample Efficiency is concerned with the total number of training it in detail later on in this chapter. But first, let's get ourselves familiar with label efficiency. ## Label Efficiency The number of labeled examples required for a model to reach the desired performance
