Originally it was used by @prashantpogde to provide extra info when drawing the DAG for debugging. SST file name alone doesn't tell which checkpoint captures the SST . I broke it with my last PR and is just restoring that here. TBH we don't even need to fill in `snapshotId` when debugging is disabled. Though it shouldn't take too much memory to store that. ########## hadoop-hdds/rocksdb-checkpoint-differ/src/main/java/org/apache/ozone/rocksdiff/CompactionNode.java: ########## @@ -0,0 +1,74 @@ +/* + * Licensed to the Apache Software Foundation (ASF) under one + * or more contributor license agreements.
