Randall Hauch updated DNA-261:
------------------------------
Fix Version/s: Future Releases
(was: 0.4)
Retargeting this to 0.5, since we've already added methods to the BinaryFactory
interface for creating binary objects from a File. This is probably sufficient for the
time being, but we can provide in the future a new implementation that incorporates the
benefits described in this issue.
Improve how Binary values are created and managed
-------------------------------------------------
Key: DNA-261
URL:
https://jira.jboss.org/jira/browse/DNA-261
Project: DNA
Issue Type: Feature Request
Components: Graph
Reporter: Randall Hauch
Priority: Minor
Fix For: Future Releases
The current InMemoryBinaryValueFactory is creating separate InMemoryBinary objects each
time 'create(...)' is called. We should have a Binary factory (and corresponding
Binary implementations) that caches the in-memory values using the content's hash as a
key. While this may slightly degrade performance (since the hash would be computed
immediately rather than lazily if needed), it could result in more efficient use of
memory. Note that we'd probably have to use weak or soft references inside the Binary
object to the cached values, so that as the Binary objects are garbage collected, the
cache can remove the unused values.
Another potential improvement is to store large values on disk, and to memory-map them
using direct buffers. This would keep large values (e.g., gigabyte-sized values, such as
those used to represent very large files) out of memory.
