In relational algebra (which SQL isn't) the union result might be one row, though only if the two input relations contained an identical tuple, eg. self-union of a one-tuple relation. - Robert Monfera.Kusto is a powerful Engine that enables us to analyze large-scale data. The Kusto Query Language (KQL) also supports graph operators, which allow us to perform complex graph operations on tabular data, such as finding paths, cycles or subgraphs. Graph operators can help us gain insights into the structure and behavior of various kinds of ...Tips. Use materialize as a replacement for join or union on fork legs. The input stream will be cached by materialize and then the cached expression can be used in join/union legs. Use batch with materialize of tabular expression statements instead of the fork operator.

There are many scenarios where graphs are useful for representing complex and dynamic data that involve many-to-many, hierarchical, or networked relationships, such as social networks, recommendation systems, connected assets, or knowledge graphs.

1. As the other answers have said, if you want all the rows in Table1 for all the rows in Table2, then a cross join (ie. a cartesian join) is the answer. On the other hand, in the scenario above, an inner join on ID would also return the same resultset: select t1.ID, t1.Name, t1.Salary, t2.Fruit.3. Answer recommended by Microsoft Azure Collective.

Result truncation is a limit set by default on the result set returned by the query. Kusto limits the number of records returned to the client to 500,000, and the overall data size for those records to 64 MB. When either of these limits is exceeded, the query fails with a "partial query failure".

A cross-cluster join involves joining data from datasets that reside in different clusters.

Copy. range TIMESTAMP from ago(4h) to now() step 1m.Materialize your column at ingestion time if most of your queries extract fields from dynamic objects across millions of rows. To use the let statement with a value that you use more than once, use the materialize () function. Try to push all possible operators that will reduce the materialized dataset and still keep the semantics of the query.Parameters. The tabular input whose records are to be matched.
