Sagar Vemuri 12b6cdeed3 Trace and Replay for RocksDB (#3837) ... Summary: A framework for tracing and replaying RocksDB operations. A binary trace file is created by capturing the DB operations, and it can be replayed back at the same rate using db_bench. - Column-families are supported - Multi-threaded tracing is supported. - TraceReader and TraceWriter are exposed to the user, so that tracing to various destinations can be enabled (say, to other messaging/logging services). By default, a FileTraceReader and FileTraceWriter are implemented to capture to a file and replay from it. - This is not yet ideal to be enabled in production due to large performance overhead, but it can be safely tried out in a shadow setup, say, for analyzing RocksDB operations. Currently supported DB operations: - Writes: -- Put -- Merge -- Delete -- SingleDelete -- DeleteRange -- Write - Reads: -- Get (point lookups) Pull Request resolved: https://github.com/facebook/rocksdb/pull/3837 Differential Revision: D7974837 Pulled By: sagar0 fbshipit-source-id: 8ec65aaf336504bc1f6ed0feae67f6ed5ef97a72		6 years ago
