These sync modes change the way data is synced between servers. This page details the two sync modes available and how they work. + +* The `DELAY` sync mode is the default sync mode, that use the `network_latency_miliseconds` value to apply a delay before listening to Redis data +* The `LOCKSTEP` sync mode uses a data checkout system to ensure that all servers are in sync regardless of network latency or tick rate fluctuations. This mode was introduced in HuskSync v3.1 + +You can change which sync mode you are using by editing the `sync_mode` setting under `synchronization` in `config.yml`. + +> **Warning:** Please note that you must use the same sync mode on all servers (at least within a cluster). + +

+ +## Delay +![Delay diagram](https://raw.githubusercontent.com/WiIIiam278/HuskSync/master/images/system-diagram.png) + +The `DELAY` sync mode works as described below: +* When a user disconnects from a server, a `SERVER_SWITCH` key is immediately set on Redis, followed by a `DATA_UPDATE` key which contains the user's packed and serialized Data Snapshot. +* When the user connects to a server, they are marked as locked (unable to break blocks, use containers, etc.) +* The server asynchronously waits for the `network_latency_miliseconds` value (default: 500ms) to allow the source server time to serialize & set their key. +* After waiting, the server checks for the `SERVER_SWITCH` key. + * If present, it will continuously attempt to read for a `DATA_UPDATE` key; when read, their data will be set from the snapshot deserialized from Redis. + * If not present, their data will be pulled from the database (as though they joined the network) + +`DELAY` has been the default sync mode since HuskSync v2.0. In HuskSync v3.1, `LOCKSTEP` was introduced. Since the delay mode has been tested and deployed for the longest, it is still the default, though note this may change in the future. + +However, if your network has a fluctuating tick rate or significant latency (especially if you have servers on different hardware/locations), you may wish to use `LOCKSTEP` instead for a more reliable sync system. + +## Lockstep +The `LOCKSTEP` sync mode works as described below: +* When a user connects to a server, the server will continuously asynchronously check if a `DATA_CHECKOUT` key is present. + * If, or when, the key is not present, the plugin will set a new `DATA_CHECKOUT` key. +* After this, the plugin will check Redis for the presence of a `DATA_UPDATE` key. + * If a `DATA_UPDATE` key is present, the user's data will be set from the snapshot deserialized from Redis contained within that key. + * Otherwise, their data will be pulled from the database. +* When a user disconnects from a server, their data is serialized and set to Redis with a `DATA_UPDATE` key. After this key has been set, the user's current `DATA_CHECKOUT` key will be removed from Redis. + +Additionally, note that `DATA_CHECKOUT` keys are set with the server ID of the server which "checked out" the data (taken from the `server.yml` config file). On both shutdown and startup, the plugin will clear all `DATA_CHECKOUT` keys for the current server ID (to prevent stale keys in the event of a server crash for instance) \ No newline at end of file diff --git a/docs/Translations.md b/docs/Translations.md index a6879a84..3a1cf06d 100644 --- a/docs/Translations.md +++ b/docs/Translations.md @@ -3,10 +3,10 @@ HuskSync supports a number of community-sourced translations of the plugin local You can change which preset language option to use by changing the top-level `language` setting in the plugin config.yml file.
