Is scylla bootstrapping inefficient?

horschi · October 9, 2023, 8:07am

Hi,

bootstrapping a new node causes a lot of compactions on the new node. Is this really necessary?

Couldn’t streaming be in token range order, where all ranges are written into one sstable? Also reshaping could be done directly when receiving, splitting data into shards.

From what I see, this is not how bootstrapping works, right?

First, yes it’s inefficient.

Streaming is done in token range order. The problem is that each node contributes some vnodes, and those vnodes are discontiguous. Therefore there is a reshaping pass after all sstables are received, to reorganize the data into one sstable.

There should be one RESHAPE compaction per shard after bootstrap, no more.

With our upcoming tablets feature, there will be no reshaping or compaction needed.

But currently there is much more than one reshape/compaction?!

Couldn’t the bootstrapping node request token ranges in order and write those into the same sstables (one per shard)?
Right now it seems to be creating many small files, I assume because its writing a separate sstable per vnode.

Does this mean there will be no imrpovement for the vnode setup? There are many users out there using vnodes, I think it would be good if vnode bootstrapping still works well. Or will there be a migration path to tablets?

That’s what there should be. If there is more, maybe there’s a bug, or I don’t understand the process will enough. @raphaelsc should know more.

We don’t request data in token order since that means only one NORMAL node will participate at a time. As it is, all NORMAL nodes (in the same rack) participate, and so they need to contribute less bandwidth.

For tablets, we plan to have an automatic migration process, though that will come some time after tablets are generally available.

The new server could ask for multiple token ranges from different nodes and merge those into one sstable, resulting into something like this:
<Token 1 from server3><Token 5 from server8><Token 9 from server2><Token 11 from server4>…

Problems are error handling and concurrency. I assume thats why scylla is not doing it like this.

Avi, I apologize for distracting you so often! But bootstrapping really feels less optimal than in Cassandra and I’d like to understand it.

It can’t ask for the ranges serially, since that’s too slow. So it asks for the range in parallel, then merges them.

Maybe there’s a bug, but we need more detailed information about compaction history to see it.

Just had a look at the logs from the weekend (grepped for one table for better readability), where I added a second node in that datacenter:

13:07:52 - 16:01:08 → Bootstrap/streaming (~ 3 hours)
16:05:47 - 17:35:30 → Reshape/compact (1 1/2 hours)

This was bootstrapping from one other node in the datacenter. I assume streaming would have been faster if there were multiple nodes in that datacenter. I have to see if I can find some logs for that.

Also this was on spinning disks.

(I had to shorten the log a little to fit in here)

11:59:54 - 12:49:19 - Bootstrap / stream (50 minutes)
12:49:19 - 13:56:15 - Reshape / compact (1 hour 7 minutes)

Adding 2nd node (previous log): 44 stream sessions / sstables
Adding 5th node (in the rack): 264 stream sessions / sstables

Conclusion:
With a larger number of nodes, number of sstables is growing and reshape is taking longer than streaming.

Please file an issue with all the information, it’s easier to track it there.

That’s actually expected. With a small number of nodes, the scheduler on the existing node will throttle the exiting node’s streaming bandwidth to preserve queries, so the new node’s disk bandwidth will not be saturated.

With a large number of nodes, each existing node needs to contribute a small amount of bandwidth, so we can saturate the new node. So streaming from a large cluster is faster than streaming from a small cluster.

Reshape takes place on the new node by itself, so its performance doesn’t depend on the cluster size.

I was refering to the relative time between streaming & reshaping. Why should reshape have a higher ratio when the cluster is larger?
In an ideal world it should not, but I think currently its because scylla creates more&smaller sstable files when clusters are larger.

btw: I am currently bootstrapping another node (again second node in DC) and its compact like crazy during streaming:

Active compaction remaining time :   0h00m00s

I still think bootstrapping would be faster if less sstables would be created and reshape would happen during streaming

Should I still open a ticket?
