sdong 4428c76181 Multi-File Trivial Move in L0->L1 (#10188) ... Summary: In leveled compaction, L0->L1 trivial move will allow more than one file to be moved in one compaction. This would allow L0 files to be moved down faster when data is loaded in sequential order, making slowdown or stop condition harder to hit. Also seek L0->L1 trivial move when only some files qualify. 1. We always try to find L0->L1 trivial move from the oldest files. Keep including newer files, until adding a new file won't trigger a trivial move 2. Modify the trivial move condition so that this compaction would be tagged as trivial move. Pull Request resolved: https://github.com/facebook/rocksdb/pull/10188 Test Plan: See throughput improvements with db_bench with fast fillseq benchmark and small L0 files: ./db_bench_l0_move --benchmarks=fillseq --compression_type=lz4 --write_buffer_size=5000000 --num=100000000 --value_size=1000 -level_compaction_dynamic_level_bytes The throughput improved by about 50%. Stalling still happens though. Reviewed By: jay-zhuang Differential Revision: D37224743 fbshipit-source-id: 8958d97f22e12bdfc14d2e85930f6fa0070e9659		3 years ago
