Same with me. I tried to figure out how the id allocation process is done but haven't found information about it. There are questions which are unclear till now:
I would appreciate seeing answers for any of those questions.
Best regards
Also it is currently not clear how cluster.max-partitions
and ids.num-partitions
are correlated and this topic is not covered by docs.
Have the same questions. When will the doc be updated? Thanks.
Any updates on this? :)
I'm not an expert, I'm just a random user who happened to go diving through the code, but... It looks like cluster.max-partitions
controls the number of partitions in the graph, but SimpleBulkPlacementStrategy
randomly picks ids.num-partitions
of them and then randomly assigns vertexes to one of that subset. There's a page which gives advice on setting cluster.max-partitions
, but I've seen no advice on how to pick ids.num-partitions
.
I know there's the documentation but it's unclear how it relates to
ids.block-size
. Can someone add more colour to the documentation please?Better explanation of using
ids.block-size
to reserve blocks of ids by each instance could be better explained too. Maybe detail somewhere what Janus does at startup etc? I'm not sure I've see that anywhere (although could have missed it).
