Re: Large sstables

What i have done is: 1) added more disks, so the compaction will carry on 2) when i've switched to LCS from STCS the STCS queues for the processing big sstables have remained, so i've stopped these queues with nodetool stop -id queue_id and LCS compaction has started to process sstables , i'm u

Re: Large sstables

If there are a lot of droppable tombstones, you could also run User Defined Compaction on that (and on other) SSTable(s). This blog post explains it well: http://thelastpickle.com/blog/2016/10/18/user-defined-compaction.html On Fri, Aug 31, 2018 at 12:04 AM Mohamadreza Rostami < mohamadrezarosta.

Re: Large sstables

Hi,Dear Vitali The best option for you is migrating data to the new table and change portion key patterns to a better distribution of data and you sstables become smaller but if your data already have good distribution and your data is really big you must add new server to your datacenter, if yo

Re: Large sstables

Either of those are options, but there’s also sstablesplit to break it up a bit Switching to LCS can be a problem depending on how many sstables /overlaps you have -- Jeff Jirsa > On Aug 30, 2018, at 8:05 AM, Vitali Dyachuk wrote: > > Hi, > Some of the sstables got too big 100gb and more s

Large sstables

Hi, Some of the sstables got too big 100gb and more so they are not compactiong any more so some of the disks are running out of space. I'm running C* 3.0.17, RF3 with 10 disks/jbod with STCS. What are my options? Completely delete all data on this node and rejoin it to the cluster, change CS to LC

Is there a way to stop cassandra compacting some large sstables?

Hi, I changed compaction strategy from 'size tiered' to 'leveled' but after running a few days C* still tries to compacting some old large sstables, say: 1. I have 6 disks per node and 6 data directories per disk 2. There are some old huge sstables generated when using '

Re: splitting large sstables

apply patch + recompile. Define "max_sstable_size" compaction strategy property on CF you want to split, then run compaction.

Re: splitting large sstables

Could you provide more details how to use it? Let's say I already have a huge sstable. What am i supposed to do to split it? Thank you, Andrey On Sat, Dec 1, 2012 at 11:29 AM, Radim Kolar wrote: > from time to time people ask here for splitting large sstables, here is > patch
