RocksDB v4.11.0 Release Notes

Release Date: 2016-08-01 // over 7 years ago

  • Public API Change

    • options.memtable_prefix_bloom_huge_page_tlb_size => memtable_huge_page_size. When it is set, RocksDB will try to allocate memory from huge page for memtable too, rather than just memtable bloom filter.

    🆕 New Features

    • 🔄 A tool to migrate DB after options change. See include/rocksdb/utilities/option_change_migration.h.
    • Add ReadOptions.background_purge_on_iterator_cleanup. If true, we avoid file deletion when destroying iterators.
