Hey guys,
I needed to migrate an index to a new cluster and after a lot of hesitating
I decided to give it a try to taskrabbit's elasticsearch-dump:
I tested it with 10k documents, which worked fine, so I decided to migrate
the real data to the new cluster with the following command:
elasticdump --input=http://oldcluster:9200/my_index
--output=http://newcluster:9200/my_index
"my_index" contains ~5 million documents, so I expected it to take a while,
but not this long. It's been running since 10 AM UTC+1 yesterday and it's
migrated only a bit over 1.5 million docs so far - in roughly 28 hours.
When it started, it indexed around 100 docs per second, by the time I went
home from work (around 5 PM UTC+1), it was only around 30 docs/s, now it's
around 10 docs/s.
Being a newbie with ElasticSearch, I don't even know how to diagnose what is
the reason of this slowness. Could you help me with this?
Keep in mind that I'm at work for 2 or 3 more hours today, but after that,
I won't have access to the servers until next Monday. Feel free to suggest
anything in that time too, I will read it and try to reply, but can't look
into anything or do anything about it.
Regards,
Attila Bukor
