HeapProfiler

risingwave_common_heap_profiling::profiler

Struct HeapProfiler 

Source 
pub struct HeapProfiler {
    config: HeapProfilingConfig,
    threshold_auto_dump_heap_profile: usize,
    jemalloc_dump_mib: dump_mib,
    opt_prof: bool,
}
Expand description

HeapProfiler automatically triggers heap profiling when memory usage is higher than the threshold.

To use it, both jemalloc’s opt.prof and RisingWave’s config heap_profiling.enable_auto must be set to true.

Fields§

§config: HeapProfilingConfig§threshold_auto_dump_heap_profile: usize§jemalloc_dump_mib: dump_mib§opt_prof: bool

If jemalloc profiling is enabled

Implementations§
