Does UNLOAD use result caching on Amazon Redshift

0

Hi,

when running an UNLOAD command on Amazon Redshift (or Redshift Serverless) with a SELECT statement attached to it.

Is the query benefiting the result caching mechanism available in Amazon Redshift ?

Result Caching

Thank you.

@semir I did a quick test on my serverless workgroup running the same UNLOAD multiple times but looks like in the SYS_QUERY_HISTORY result_cache_hit column was always "false". I assume this means UNLOAD will not use the result set cache.

  • thank you Ranjan for your time; what about Provisionned (I know the result caching is managed a bit differently)?
