> Performance Improvements for HBase Scan
> ---------------------------------------
>
> Key: IMPALA-1405
> URL: https://issues.apache.org/jira/browse/IMPALA-1405
> Project: IMPALA
> Issue Type: New Feature
> Components: Perf Investigation
> Affects Versions: Product Backlog
> Reporter: Martin Grund
> Priority: Minor
> Labels: performance
>
> This is a ticket to track the efforts to improve the performance of the HBase
> scan by first batching intermediate results and reducing the number of JNI
> calls between backend and the HBase client.
> The plan is to provide a layer between the backend and the HBase client that
> takes care of building the HBase scan and buffering of intermediate results.
> Optimally this layer uses allocated memory from the backend to directly store
> the tuples in Impalas native format.
