The execution plan for a specific Amazon Redshift query statement breaks down execution and calculation of a query into a discrete sequence of steps and table operations that eventually produce a final result set for the query. For information about query planning, seeQuery processing. ...

but I am kind of disappointed that the 1/1/x trick did not work - so I'm not seeking an ANSWER to the problem I had, just an EXPLANATION of why the calculated value won't work in the formula, especially when two steps were involved and the calculated cell (C1) clearly ...
The second step in processing a traversal is to convert its TinkerPop steps into a set of converted and non-converted Neptune steps. Most steps in the Apache TinkerPop Gremlin query language are converted to Neptune-specific steps that are optimized to run on the underlying Neptune engine. When...
These steps are expressed as a set of database operators that consume and produce rows. The order of the operators and their implementations is decided by the query optimizer using a combination of query transformations and physical optimization techniques. While the display is commonly shown in a...
Query processing can be divided into 7 phases: Steps [1]-[6] are handled by the parser. Step [7] is the execution of the statement. The explain plan is produced by the parser. Once the access path has been decided upon it is stored in the library cache together with the statement it...
indexes— Shows used indexes, the number of filtered parts and the number of filtered granules for every index applied. Default: 0. Supported for MergeTree tables. actions— Prints detailed information about step actions. Default: 0. json— Prints query plan steps as a row in JSON format. Def...
They defined the output format as |special_token|<reasoning_process> |special_token|, Here the reasoning process is the Chain of Thought for the query. The chain of thought is the reasoning process the model used to arrive at the answer. It shows the steps and logic involved and the summa...
