On the cloud platform of Camptocamp, a shared redis is used to store the sessions of the different projects -> the number of keys is huge, and using an iterative match kills the performance because of the networking overhead. We switch to using redis.key(pattern), and since the pattern typically has a leading string which will allow redis to find the correct bucket, the performance should be good.
Sessions in Redis ================= This addon allows to store the web sessions in Redis. Configuration ------------- The storage of sessions in Redis is activated using environment variables. * ``ODOO_SESSION_REDIS`` has to be ``1`` or ``true`` * ``ODOO_SESSION_REDIS_HOST`` is the redis hostname (default is ``localhost``) * ``ODOO_SESSION_REDIS_PORT`` is the redis port (default is ``6379``) * ``ODOO_SESSION_REDIS_PASSWORD`` is the password for the AUTH command (optional) * ``ODOO_SESSION_REDIS_SSL`` is the SSL connection (default is ``true``) (optional) * ``ODOO_SESSION_REDIS_SSL_CERT_REQS`` is the SSL certificate requirements (default is ``required``), needed to be disabled when using self-signed certificates (optional) * ``ODOO_SESSION_REDIS_CLUSTER`` the redis in cluster mode (default is ``false``) (optional) * ``ODOO_SESSION_REDIS_URL`` is an alternative way to define the Redis server address. It's the preferred way when you're using the ``rediss://`` protocol. * ``ODOO_SESSION_REDIS_PREFIX`` is the prefix for the session keys (optional) * ``ODOO_SESSION_REDIS_EXPIRATION`` is the time in seconds before expiration of the sessions (default is 7 days) * ``ODOO_SESSION_REDIS_EXPIRATION_ANONYMOUS`` is the time in seconds before expiration of the anonymous sessions (default is 3 hours) The keys are set to ``session:<session id>``. When a prefix is defined, the keys are ``session:<prefix>:<session id>`` This addon must be added in the server wide addons with (``--load`` option): ``--load=web,session_redis`` Limitations ----------- * The server has to be restarted in order for the sessions to be stored in Redis. * All the users will have to login again as their previous session will be dropped. * The addon monkey-patch ``odoo.http.Root.session_store`` with a custom method when the Redis mode is active, so incompatibilities with other addons is possible if they do the same.
