ExecutorResourceMgr_Namespace::ChunkRequestInfo Struct Reference

Specifies all DataMgr chunks needed for a query step/request, along with their sizes in bytes. It also keeps track of other metadata to avoid having to recompute this info, such as total_bytes and a vector of total byte sizes for each kernel. The latter is relevant if bytes_scales_per_kernel is true, as the ExecutorResourceMgr/ ExecutorResourcePool can scale back the number of kernels allowed to run simultaneously to ensure that a query step can run.

Detailed Description

Specifies all DataMgr chunks needed for a query step/request, along with their sizes in bytes. It also keeps track of other metadata to avoid having to recompute this info, such as total_bytes and a vector of total byte sizes for each kernel. The latter is relevant if bytes_scales_per_kernel is true, as the ExecutorResourceMgr/ ExecutorResourcePool can scale back the number of kernels allowed to run simultaneously to ensure that a query step can run.
