Philipp Moritz created ARROW-2953: ------------------------------------- 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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
