-------------------------------
Summary: Remove the dependency of StateBenchmark on
RocksDBKeyedStateBackend APIs.
Key: FLINK-36622
URL: https://issues.apache.org/jira/browse/FLINK-36622
Project: Flink
Issue Type: Improvement
Components: Runtime / State Backends
Affects Versions: 2.0-preview
Reporter: Han Yin
Fix For: 2.0.0
Currently, flink-benchmarks relies on non-public APIs in Flink. For example, in
{_}+StateBackendBenchmarkUtils.java+{_}, the function _+compactState+_ takes
RocksDBKeyedStateBackend as its first argument.
This requires explicit type conversion in flink-benchmark(from
+_KeyedStateBackend_+ to {+}_RocksDBKeyedStateBackend_{+}). Moreover, this
means that once the signature of +_RocksDBKeyedStateBackend_+ changes, we need
to modify flink-benchmark correspondingly.
Therefore, we should avoid exposing non-public APIs in
{_}+StateBackendBenchmarkUtils+{_}.
