In replication schema if one of the instances was powered off, it isn't
detected by others and the connection hangs. Alive machines show
'follow' state. Add timeout to solve this issue. It's safe since
applier and relay both send messages every replication_timeout so we can
assume that if we read nothing we have problem with connection. Use
replication_disconnect_timeout which is replication_timeout * 4 as for
now.

The test fixed and comments improved by @locker.

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.
