Yanqin Jin fee2c472d0 Include minimal contextual information in `CompactionIterator` (#10505) ... Summary: The main purpose is to make debugging easier without sacrificing performance. Instead of using a boolean variable for `CompactionIterator::valid_`, we can extend it to an `uint8_t`, using the LSB to denote if the compaction iterator is valid and 4 additional bits to denote where the iterator is set valid inside `NextFromInput()`. Therefore, when the control flow reaches `PrepareOutput()` and hits assertion there, we can have a better idea of what has gone wrong. Pull Request resolved: https://github.com/facebook/rocksdb/pull/10505 Test Plan: make check ``` TEST_TMPDIR=/dev/shm/rocksdb time ./db_bench -compression_type=none -write_buffer_size=1073741824 -benchmarks=fillseq,flush ``` The above command has a 'flush' benchmark which uses `CompactionIterator`. I haven't observed any CPU regression or drop in throughput or latency increase.
