Re: one point optimisation
Posted by ALEKSEY KUZNETSOV <al...@gmail.com>.
Hi! Your talking about node ordering?
What is the point of the ordering?
How is it implemented?
Thanks for the answering in advance!

Re: one point optimisation
Posted by Alexey Goncharuk <al...@gmail.com>.
This optimization does not work when near cache is enabled because we need
the same ordering on near nodes. You should see the expected number of
messages with near cache disabled.

Aleksey,
The blog describes the 1-phase commit at a high level, but I am still
curious about the differences you found. Can you share them here?

Regarding IgniteOnePhaseCommitNearSelfTest test , ignite's one phase
optimisation works not as you said.
I attached picture of message exchange. There are partial prepare phase
exists, along with finish phase.

As far as I know a partition is always allocated to a specific node and does not span nodes. Ignite has default 1024 partitions on start that are split equally across nodes.

in ur blog u texted belonging to the same partition is nessesary for 1
phase commit. But its not guarantee belonging to the same node. Partition
may span many nodes
