Pindikura Ravindra created ARROW-5482: -----------------------------------------
Summary: reduce heap footprint of ValueVectors Key: ARROW-5482 URL: https://issues.apache.org/jira/browse/ARROW-5482 Project: Apache Arrow Issue Type: Task Components: Java Reporter: Pindikura Ravindra Assignee: Pindikura Ravindra In some scenarios, we hold lots of value vectors in memory eg. during join, aggregation. The heap analysis shows that the costs are as follows for a simple IntVector (used VisualVM on mac) : IntVector : 80 bytes vector.types.pojo.FieldType : 41 bytes vector.types.pojo.Field : 40 bytes IntReaderImpl : 28 bytes I'll use this Jira to track ways to reduce the heap usage. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
