Hi, All
In page https://wiki.apache.org/jackrabbit/Clustering, there is several
caveats if the janitor thread is enabled. One of the caveats is as below
If the janitor is enabled then you loose the possibility to easily add
cluster nodes. (It is still possible but takes detailed knowledge of
Jackrabbit.)
>From the statement, it looks we could not directly adding new node into the
cluster environment if some old journals have already been deleted by
janitor thread. But based on my current understanding, during the startup,
every new node always does following 2 things sequentially:
1. Reading the whole repository, including all nodes and the version
history, and built index for them
2. Read all revisions to sync
You see, for new added node, since step#1 already reads all nodes from
database, even some revisions are already removed, step#2 seems has no
problem.
If step#2 does have any problem, or if there is any other potential issue.
Please let me know or give me one example.
Regard,
-Liang
