How to configure MongooseIM to use CETS instead of Mnesia
CETS Config Example
CETS is a library, which allows to replicate in-memory data across the MongooseIM cluster. It could be used to store:
- information about online XMPP sessions;
- information about outgoung S2S connections;
- stream management session IDs;
- information about online MUC rooms.
If you want to use CETS instead of Mnesia, ensure that these options are set:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20
outgoing_pools are configured with RDBMS, so CETS could get a list of MongooseIM nodes, which use the same
relational database and cluster them together.
A preferred way to install MongooseIM is Helm Charts on Kubernetes, so it allows
cets and the values would be applied using Helm's templates
CETS with the file discovery backend
It is possible to read a list of nodes to cluster from a file. But MongooseIM does not modify this file, so it is the task for the operator to update the file. But MongooseIM would reread the file without the restart:
1 2 3
And the format of the
node_list_file file is a new line separated list of nodes:
1 2 3
File backend for CETS is only useful if you do not use an RDBMS database. You could use some external script to get the list of nodes from the AWS CLI command or some other way.
