For each database, a primary storage and one or more secondary\nstorages may be defined. The secondary storages will automatically\nreplicate data from the primary storage.\n\nReplication is superior to back-ups because as long as secondaries are\nrunning, secondary data is kept updated. In the event of a failure of\na primary storage, just reconfigure a secondary to be the primary, and\nit can begin handling application requests.\n\n.. contents::\n\nFeatures\n========\n\n- Primary/secondary replication\n\n- Support for read-only secondary storages\n\nRequirements\n============\n\n- ZODB 3.9 or later.\n\nInstallation\n=============\n\nZRS is installed like any other Python package, by installing the\n``zc.zrs`` package with `easy_install\n<http://peak.telecommunity.com/DevCenter/EasyInstall>`_, `zc.buildout\n<http://pypi.python.org/pypi/zc.buildout>`_, `pip\n<http://pypi.python.org/pypi/pip>`_, etc.\n\nUsing ZRS\n=========\n\nZRS provides two ZODB storage implementations: a primary storage and a\nsecondary storage. Both storages are used with file storages.\n\n- The primary storage is a readable and writable storage.\n\n- The secondary storage is read-only.\n\n  A secondary storage can be used by read-only application clients to\n  reduce server load.\n\n  Secondary storages replicate from primary storages, or other\n  secondary storages.\n\nTheoretically, ZRS storages can be used wherever a ZODB storage would\nbe used.  In practice, however, they're used in ZEO servers.\n\nConfiguration with ZConfig\n--------------------------\n\nIf using an application, like a ZEO server or Zope, that uses `ZConfig\n<http://pypi.python.org/pypi/ZConfig>`_ to configure ZODB storages,\nthe configuration of a ZRS primary or secondary storage may be\nincluded in the configuration file as with any other storage e.g, to\nconfigure a primary storage, use something like::\n\n  %import zc.zrs\n\n  <zrs>\n   replicate-to 5000\n\n   <filestorage>\n       path /path/to/data/file\n   </filestorage>\n  </zrs>\n\nHere is a line-by-line walk through::\n\n  %import zc.zrs\n\nThe import statement is necessary to load the ZConfig schema\ndefinitions for ZRS.\n\n::\n\n  <zrs>\n\nThe zrs section defines a ZRS storage. A ZRS storage may be a primary\nstorage or a secondary storage.  A ZRS storage without a\n``replicate-from`` option (as in the example above) is a primary\nstorage.\n\n::\n\n  replicate-to 5000\n\nThe replicate-to option specifies the replication address. Secondary\nstorages will connect to this address to download replication\ndata. This address can be a port number or a host name (interface\nname) and port number separated by a colon.\n\n::\n\n  <filestorage>\n    path /path/to/data/file\n  </filestorage>\n\nA ZRS storage section must include a filestorage section specifying a\nfile storage to contain the data.\n\nConfiguring a secondary storage is similar to configuring a primary\nstorage::\n\n  %import zc.zrs\n\n  <zrs>\n   replicate-from primary-host:5000\n   replicate-to 5000\n   keep-alive-delay 60\n\n   <filestorage>\n       path /path/to/secondary/data/file\n   </filestorage>\n  </zrs>\n\nFor a secondary storage, a ``replicate-from`` option is used to specify\nthe address to replicate data from.\n\nBecause primary and secondary storages are generally on separate\nmachines, the host is usually specified in a ``replicate-from``\noption.\n\nA secondary storage can also specify a ``replicate-to`` option.  If this\noption is used, other secondary storages can then replicate from the\nsecondary, rather than replicating from the primary.\n\nSecondary storages also support the following optional option:\n\nkeep-alive-delay SECONDS\n  In some network configurations, TCP connections are broken after\n  extended periods of inactivity.  This may even be done in a way that\n  a client doesn't detect the disconnection.  To prevent this, you can\n  use the ``keep-alive-delay`` option to cause the secondary storage\n  to send periodic no-operation messages to the server.\n\nCode and contributions\n======================\n\nhttps://github.com/zc/zrs\n\n\nRecent Changes\n==============\n\nFor earlier changes, see the `HISTORY.rst <HISTORY.rst>`_.\n\n3.1.0 (2017-04-07)\n------------------\n\n- Python 3 (3.4 amd 3.5) support.\n\n  3.6 support will be added when Twisted supports Python 3.6.\n  (There are worrying test failures under Python 3.6.)\n\n- Minor convenience change to API: When instantiating primary or\n  secondary servers, you can pass a file-name instead of a storage\n  instance and a file storage will be created automatically.\n\n\n3.0.0 (2017-04-04)\n------------------\n\n- Add support for ZODB 5\n\n- Drop ZooKeeper support.",
