Specify a scanner cache that will be filled before the Scan result is returned, setting setCaching to the number of rows to cache before returning the result. By default, the caching setting on the table is used. The goal is to balance IO and network load.

Syntax

Connect-ApacheHBase -ScannerCaching string

Data Type

cstr

Default Value

"0"

Remarks

It means there is no cache for the scanner if it is less than or equal to 0. A suitable cache value can improve query efficiency, but it can also introduce additional memory usage.
