When running JFR profiling for Google BigQuery JDBC driver, I saw large amount of samples points to
Map.containsKeyfunction.When I tried local changes to BQ Java SDK to avoid
containsKeycall and callget()instead & validate if result is null or not, calls togetfunction, they don't generate as many samples.Due to
containsKeyoverride missing, it falls back to the defaultMap.containsKeyimplementation which seems to be more expensive in the case ofGenericDataclass. I didn't run sampler with these changes, but attaching results whencontainsKeywas replaced withget()in the SDK.
