-------------------------------------
Summary: [Plasma] Store memory usage
Key: ARROW-2953
URL: https://issues.apache.org/jira/browse/ARROW-2953
Project: Apache Arrow
Issue Type: Improvement
Reporter: Philipp Moritz
While doing some memory profiling on the store, it became clear that at the
moment the metadata of the objects takes up much more space than it should. In
particular, for each object:
* The object id (20 bytes) is stored three times
* The object checksum (8 bytes) is stored twice
* data_size and metadata_size (each 8 bytes) are stored twice
We can therefore significantly reduce the metadata overhead with some
refactoring.
