If the performance isn't the same or better, we clear all DOP feedback and trigger a reanalysis of the query starting from the compiled DOP.See Degree of parallelism (DOP) feedback. Cardinality estimation feedback Identifies and corrects suboptimal query execution plans for repeating queries, ...
During optimization and initial compilation, this feature propagates cardinality estimates that are based on actual table variable row counts. This accurate row count information optimizes downstream plan operations. See Table variable deferred compilation. Approximate query processing with APPROX_COUNT_...
Just add any metadata tag to your spans and, as long as its cardinality within a trace is not too high, you will be able to filter by it right away in your Traces UI. Learn more about Tracing Monitor your Couchbase with Sumo Logic February 11, 2022 Couchbase is a distributed documen...
But the cardinality of such an algebra is at most while the cardinality of is , and Cantor’s theorem then gives a contradiction. To resolve this problem, we give a coarser -algebra than the Borel -algebra, namely the Baire -algebra , thus coarsening the measurable space structure on to ...
Since aggregation over hash-encoded columns is slower than over value-encoded columns, value encoding may be specified as a hint for such columns. It is not guaranteed that the preference is applied. It is a hint as opposed to a setting. To specify an encoding hint, set the EncodingHint ...
Let be a measure-preserving system – a probability space equipped with a measure-preserving translation (which for simplicity of discussion we shall assume to be invertible). We will informally think of two points in this space as being “close” if for some that is not too large; this all...

Cardinality’s official, non-database dictionary definition is mathematical: the number of values in a set. When applied to databases, the meaning is a bit different: it’sthe number of distinct values in a table column relative to the number of rows in the table. Repeated values in the ...
