Liya Fan created ARROW-5898: ------------------------------- Summary: [Java] Provide functionality to efficiently compute hash code for arbitrary memory segment Key: ARROW-5898 URL: https://issues.apache.org/jira/browse/ARROW-5898 Project: Apache Arrow Issue Type: New Feature Components: Java Reporter: Liya Fan Assignee: Liya Fan
This issue adds a functionality to efficiently compute the hash code for a consecutive memory region. This functionality is important in practical scenarios because it helps: * Avoid unnecessary memory copy. * Avoid repeated conversions between Java objects & Arrow buffers. Since the algorithm for calculating hash code has significant performance implications, we need to design an interface so that different algorithms can be easily introduces as a plug-in. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
