Hi Guillaume,
Yes, it helps. Thanks! I can log these every hour (say) and plot the curve
over a week to get an idea of rate and its variability.

Hi Tom,
Use the wsrep_replicated_bytes and wsrep_received_bytes status variables.
The sum of those two variables will give you the total bytes written to
gcache. By using a derivative function you should be able to figure out the
write rate.
Hope this helps,

Hi Guillaume,
What variable(s) should we monitor to estimate the rate at which gcache is
written? or to otherwise estimate how far back a given gcache.size goes in
history?

Hi Bertrand,
You don't want your partitioned node to do SST, because IST is obviously
faster.
IST should always happen, unless the node has lost state (crash,
inconsistent data, etc) or the latest writeset is not found in the galera
cache.
So, rule of thumb is to have a galera cache big enough, so
Hi all,
I'm using MariaDB Cluster with 3 servers and I often have split brain
because of network. When a network split brain happen, only one node is
disconnected.
What is for you the best choice for SST or maybe IST method for this
configuration ? (N.B.: I already tried rsync method but i'm not re
5 matches
