trait RapidsBufferId extends AnyRef
An identifier for a RAPIDS buffer that can be automatically spilled between buffer stores. NOTE: Derived classes MUST implement proper hashCode and equals methods, as these objects are used as keys in hash maps. Scala case classes are recommended.

getDiskPath(diskBlockManager: RapidsDiskBlockManager): File
Generate a path to a local file that can be used to spill the corresponding buffer to disk.
Generate a path to a local file that can be used to spill the corresponding buffer to disk. The path must be unique across all buffers unless canShareDiskPaths is true.

canShareDiskPaths: Boolean
Indicates whether the buffer may share a spill file with other buffers.
Indicates whether the buffer may share a spill file with other buffers. If false then the spill file will be automatically removed when the buffer is freed. If true then the spill file will not be automatically removed, and another subsystem needs to be responsible for cleaning up the spill files for those types of buffers.
