---------------------------------
Summary: Expose splitKeyRanges in the C++ clients
Key: KUDU-3071
URL: https://issues.apache.org/jira/browse/KUDU-3071
Project: Kudu
Issue Type: Improvement
Components: client, perf
Reporter: Andrew Wong
KUDU-2437 introduced the server-side ability to return "split keys" that
logically divide a given tablet into key ranges. KUDU-2670 introduced an
improvement in the Spark integration's KuduRDD to allow for Spark to use this
generate smaller-scoped scan tokens that each scan a chunk of a tablet instead
of entire tablets. This decoupled the a table's partitioning scheme from its
read concurrency limitations.
It'd be great if we could expose chunked-token-hydration in the C++ client so
that Impala can begin generating these chunked tokens and then hydrating them
into smaller scanners in its backend.
