Approximated query The features of data sampling are listed below: -- Data sampling is a determined mechanism. The result of the same `SELECT .. SAMPLE` query is always the same. +- Data sampling is a deterministic mechanism. The result of the same `SELECT .. SAMPLE` query is always the same. - Sampling works consistently for different tables. For tables with a single sampling key, a sample with the same coefficient always selects the same subset of possible data. For example, a sample of user IDs takes rows with the same subset of all the possible user IDs from different tables. This allows using the sample in subqueries in the `IN` clause, as well as for manually correlating results of different queries with samples. -- Sampling allows reading fewer data from a disk. Note that for this you must specify the sampling key correctly.
