vsellier added a comment to T3357: Perform some tests of the cassandra storage on Grid5000.

The run with 8 nodes was faster[1] than the previous ones, as expected, but it seems it could have been even faster because the bottleneck are now the 6 replayers which have a really high load.
The performance is better between 60% to 100% depending of the object.

News for the last incomplete run with 4 nodes[1], it seems it's 25% faster then with 3 nodes which it's great
The next run will be this night with 8 cassandra nodes

vsellier added a comment to T3357: Perform some tests of the cassandra storage on Grid5000.

During the last run, I discovered there were cassandra logs[1] about oversized mutations on this run and all the previous ones.
It means some changes were committed but ignored when the commit log is flushed which it's absolutely wrong.

vsellier added a comment to T3357: Perform some tests of the cassandra storage on Grid5000.

A replay was run during all the previous night during 13 hours with the current default consistency=ONE. It can be used as the reference for the next test with the LOCAL_QUORUM consistency.
After trying several options to render the result, the simpler was to export the content of a spreadsheet in a hedgedoc document [1] .
The data are stored on a prometheus instance on a proxmox vms so it will always possible to improve the statistics later.

A new run was launched with 4x10 replayers per object type.
A limit is still reached for the revision replayers which ends with read timeout.
A test with only the revision replayers shows the problems start to append when the number of // replayers is greater than ~20

vsellier added a comment to T3396: cassandra - allow to configure the consistency level used by the queries.

One example of the wrong behavior of the read consistencty level ONE for read requests:
One of the probe of the monitoring query is based on the objectcount table content.
The servers were hard stopped after the end of the grid5000 resrvation and it seems some replication messages were lost. After the restart the content of the table in not in sync on all the servers.

vsellier added a comment to T3357: Perform some tests of the cassandra storage on Grid5000.

A first run was launched with 4x20 replayered per object type.
It seems it's too much for 3 cassandra nodes. The default 1s timeout for cassandra reads is often reached.
It's seems the batch size of 1000 is also too much for some object types like snapshots
A new test will be launched this night with some changes:

  • reduce the number of replayers processes to 4x10 per object type
  • reduce the journal client batch size to 500

vsellier added a comment to T1526: Install a new VPN endpoint at Rocquencourt.

Regarding the recurrent disconnection of the azure VPN, it seems the only difference is on the reauth=no activated on louvre but not on opnsense.
The option was activated on opnsense too, the connection should not killed anymore on a key renegociation (if I have well undertood ;))

vsellier added a comment to T3357: Perform some tests of the cassandra storage on Grid5000.

These are the first tests that will be executed:

  1. baseline configuration : 3 cassandra nodes (parasilo[1]), commitlog on a dedicated SSD, data on 4 HDD. Goal: testing minimal configuration (a night or a complete weekend if possible)
  2. baseline configuration + 1 cassandra nodes. Goal: Testing the performance impact of having 1 more server (duration enough to have tendencies)
  3. baseline configuration + 3 cassandra nodes: Goal: Testing the performance impact of having the cluster size x 2 (duration enough to have tendencies)
  4. baseline configuration but with the commitlog on the data partition. Goal check the impact of data/commitlog mutualization (duration enough to have tendencies)
  5. baseline configuration but with 2 HDD. Goal check the impact of the number of disks + have a reference for the next run (a night)
  6. baseline configuration but with 2 HDD + commitlog on a dedicated HDD. Goal check the impact of having the commitlog on a slower disk (duration enough to have tendencies)
  7. baseline configuration but with 2x the default heap allocated to cassandra. Goal check the impact of the memory configuration ((!) check the gc profile)

vsellier added a comment to T3394: cassandra - origin url hashing encoding issue.

Thanks, it was tested this night on grid5000, all the origins were correctly replayed without issues.
