> It is much lower than non blob. What should this value be set to? https://github.com/facebook/rocksdb/wiki/BlobDB#performance-tuning - `target_file_size_base`: the target size of SST files. Note that even when using BlobDB, it is important to have an LSM tree with a “nice” shape and multiple levels and files per level to prevent heavy compactions. Since BlobDB extracts and writes large values to blob files, it makes sense to make this parameter significantly smaller than the memtable size, for instance by dividing up the memtable size proportionally based on the ratio of key size to value size. - `max_bytes_for_level_base`: consider setting this to a multiple (e.g. 8x or 10x) of target_file_size_base. -- This is an automated message from the Apache Git Service.
