Benefits of Result Caching
Result caching can provide significant performance improvements for applications that execute the same query multiple times. When a query is executed, the result set is stored in the cache. When the same query is executed again, the result set is retrieved from the cache instead of re-executing the query. This reduces the amount of time required to retrieve the data as well as the number of resources (CPU, memory, etc.) required to execute the query.
What is Result Caching in Oracle?
Result Caching is a feature of the Oracle database that allows query results to be stored in memory, eliminating the need to re-execute the query and improving overall query performance. It can be used in both single-instance and clustered environments to reduce physical I/O and improve the scalability of an Oracle database.
When a query is executed in Oracle, the database needs to access data from the disk, process it, and then return the results. This process can be quite time-consuming and can also require a significant amount of physical I/O. Result Caching eliminates the need to access the disk and process the data, instead storing the results in memory and allowing subsequent requests to access the cached results.
