There are several standardized algorithms for that. In PostgreSQL, there are a number of functions that generate UUID s: The uuid-ossp extension offers functions to generate UUID s.The uuid_generate_random() function forces the use of the all-random UUID format, even if a high-quality random number generator is not available, in which case a pseudo-random generator will be substituted.

In practice, I've rarely seen a 5 row table scale to millions of rows without notice. TABLESAMPLE() seems to base selection of the number of pages in a table, so the given row size influences what comes back. The point of table sample, at least as I see it, is to give you a good sub-set from which you can select -- kind of like a derived table.Using the UUID class is probably fast enough for most scenarios, though I would expect that some specialized hand-written variant, which does not need the postprocessing, to be faster. Anyway, the bottleneck of the overall computation will normally be the random number generator. In case of the UUID class, it uses SecureRandom.It produces this result: array_to_string ----- 1,2,3,4,5,6,7,8,9 See Looping through arrays in PL/pgSQL.This shows how you can use the FOREACH loop in procedural code, with an appropriate value for the SLICE operand, to unnest an array into a set of subarrays whose dimensionality you can choose. At one end of the range, you can mimmic unnest() and produce scalar values.

Cloud Spanner does not implement a sequence generator, and it is not a Spanner best practice to use sequential IDs because doing so can cause hotspotting. An alternative mechanism of generating a unique primary key is to use a UUID or any other similar mechanisms that result in non-sequential values.One way to avoid hotspots is to use the UUID to generate unique Ids. As defined by wikipedia a UUID is " A UUID is simply a 128-bit value. The meaning of each bit is defined by any of several variants." By default there is no UUID function in AWS Redshift. However with the python UDF you can easily create a UUID function in Redshift.List of juice wrld unreleased songsUsed hellcat engine for sale
