MyRocks exposes both, so you can enable cache_index_and_filter_with_high_priority while leaving cache_high_pri_pool_ratio at zero. That seems like a...
For background see http://smalldatum.blogspot.com/2018/07/default-options-in-myrocks.html . I want MyRocks to have better default behavior without setting rocksdb_default_cf_options. These are default values that are lousy for performance and we when discussing with...
The state of the LSM tree (data in memtable, #files in L0) is a significant source of variance for performance on read-only and read-heavy tests. This is much worse for...
This is a discussion. Eventually it might become a feature request. The old InnoDB used a few files for all tables. InnoDB compression requires file-per-table and with that there is...
Summaries are printed every N inserts or queries. I want an option to do this every N seconds.
