is hbase backend eventually consistent

Jerry He <jerr...@...>
 

HBase is strong consistency (as compared to eventual consistency).

I agree the chapter is confusing.  What it says is that because the backends lack multiple row transaction consistency (for both Cassandra and HBase, as compared to a ACID system), JanusGraph employs some home-made mechanisms to support transaction consistency.  The mechanism takes into consideration and covers the 'eventual consistency' issue as well (for Cassandra).

Hope this helps.

I have red here : https://docs.janusgraph.org/latest/eventual-consistency.html that hbase is "eventually consistent". However, as far as I know Hbase is strongly consistent, at the row level.

I don't understand ... has it something to do with the fact that hbase is not consistent when multiple rows are involded, or a way of configuring hbase that I do not know about ?

Thanks !
