Member Enumeration Documentation

BlockSize

enum AZ::IO::BlockCacheConfig::BlockSize : u32

Dynamic options for the blocks size. It's possible to set static sizes or use the names from this enum to have AZ::IO::Streamer automatically fill in the sizes. Fixed sizes are set through the Settings Registry with "BlockSize": 524288, while dynamic values are set like "BlockSize": "MemoryAlignment". In the latter case AZ::IO::Streamer will use the available hardware information and fill in the actual value.

Enumerator
MaxTransfer	The largest possible block size.
MemoryAlignment	The size of the minimal memory requirement of the storage device.
SizeAlignment	The minimal read size required by the storage device.
