# Store constant AMR arrays with less memory
|
||
|
|
|
||
|
|
The `AmrArrays` filter generates some cell fields that specify information
|
||
|
|
about the hierarchy, which are constant across all cells in a partition.
|
||
|
|
These were previously stored as an array with the same value throughout.
|
||
|
|
Now, the field is stored as an `ArrayHandleConstant`, which does not
|
||
|
|
require any real storage. Recent changes to VTK-m allow code to extract the
|
||
|
|
array as a component efficiently without knowing the storage type.
