Replace box.info.vinyl().performance.iterator.{run,mem} global counters
with the following per index counters:

  memory
    iterator
      lookup            # number of lookups in the memory tree
      get               # number of statements returned by mem iterator
        rows
        bytes

  disk
    iterator
      lookup            # number of lookups in the page index
      get               # number of statements returned by run iterator
        rows
        bytes

      bloom             # number of times bloom filter
        hit             #   allowed to avoid a disk read
        miss            #   failed to prevent a disk read

      read              # number of statements actually read from disk
        rows
        bytes

Tarantool is an in-memory database and application server.

Key features of the application server:

  • 100% compatible drop-in replacement for Lua 5.1, based on LuaJIT 2.1. Simply use #!/usr/bin/tarantool instead of #!/usr/bin/lua in your script.
  • full support for Lua modules and a rich set of own modules, including cooperative multitasking, non-blocking I/O, access to external databases, etc

Key features of the database:

  • MsgPack data format and MsgPack based client-server protocol
  • two data engines: 100% in-memory with optional persistence and a 2-level disk-based B-tree, to use with large data sets
  • multiple index types: HASH, TREE, RTREE, BITSET
  • asynchronous master-master replication
  • authentication and access control
  • the database is just a C extension to the app server and can be turned off

Supported platforms are Linux/x86 and FreeBSD/x86, Mac OS X.

Tarantool is ideal for data-enriched components of scalable Web architecture: queue servers, caches, stateful Web applications.

To download and install Tarantool as a binary package for your OS, please visit https://tarantool.org/download.html.
