Struct dittolive_ditto::transport::Global
source · [−]Expand description
Settings not associated with any specific type of transport.
Fields
sync_group: u32
The sync group for this device.
When peer-to-peer transports are enabled, all devices with the same App
ID will normally form an interconnected mesh network. In some
situations it may be desirable to have distinct groups of devices
within the same app, so that connections will only be formed within
each group. The sync_group
parameter changes that group
membership. A device can only ever be in one sync group, which
by default is group 0. Up to 2^32 distinct group numbers can be used in
an app.
This is an optimization, not a security control. If a connection is
created manually, such as by specifying a connect
transport, then
devices from different sync groups will still sync as normal. If
two groups of devices are intended to have access to different data
sets, this must be enforced using Ditto’s permissions system.
routing_hint: u32
The routing hint for this device.
A routing hint is a performance tuning option which can improve the performance of applications that use large collections. Ditto will make a best effort to co-locate data for the same routing key. In most circumstances, this should substantially improve responsiveness of the Ditto Cloud.
The value of the routing hint is application specific - you are free to chose any value. Devices which you expect to operate on much the same data should be configured to use the same value.
A routing hint does not partition data. The value of the routing hint will not affect the data returned for a query. The routing hint only improves the efficiency of the Cloud’s ability to satisfy the query.
