    Clustered storage
    #1 by mrslavutich on Nov 16, 2017 4:23:18 PM

    I have configured jackrabbit clustering via postgres on a workspace between the author and two public nodes. It turns out that the author and the public refer to a separate database for this workspace for read and write data. As a result, the point of failure of this particular database is very high, additional replication is needed. How best to make this replication, for example via master-slave, standard postgres tools? Explain why you need journal in this separate database, it records changes, and then how is journal used?

    Hi Vyacheslav,

    i guess these questions are more a part of jackrabbit configuration. Please also have a look at https://wiki.apache.org/jackrabbit/Clustering

    The description of fault tolerance is not described there. I'm more interested in how the synchronization based on the journal should work. When synchronizing data through a jackrabbit cluster, should the data be replicated to the databases of each instance? I set up the cluster and see that the changes in the clustered repository are only in the separate database, but not in local. Maybe they are written to the cache or to the index, because if I stop the clustered separate database the data in the nodes is pulled out.
