Sampling "without replacement" means that no item will appear more than once. To use it simply pass in the sampling probability into the UDF's constructor and then pass in a bag to be sampled.

If you enable the trace sampling mechanism at the server-side, you will find that the service metrics, service instance, endpoint, and topology all have the same accuracy as before.

Sampling without replacement requires one additional pass over the RDD to guarantee sample size, whereas sampling with replacement requires two additional passes. Find full example …

To perform the balance sampling for independent groups, use the 'grouping_cols' parameter. Note below that each group (zone) has a different count of the classes (mainhue), with some groups …

Scalable simple random sampling with replacement (ScaSRSWR). This UDF together with SimpleRandomSampleWithReplacementElect implement a scalable algorithm for simple …

Description The TABLESAMPLE statement is used to sample the table. It supports the following sampling methods:

Sampling: simple random sample with/without replacement, weighted sample, sample by keys Hashing: SHA and MD5 Link Analysis: PageRank Assorted Macros: deduplication of tables, …

The up-front / p-sampling option of the Theta Sketches exists to address the system-level storage allocation challenge when dealing with highly partitioned/fragmented massive data that …

When the agent receives the task, it periodically samples the thread stack related to the endpoint when requested. Once the sampling is complete, the thread stack within the endpoint can be …

The random sampling module consists of useful utility functions for sampling operations. These functions can be used while implementing new algorithms. Functions Sample a single row …
