Reindex performance


(Derrick) #1

Hi,

I am using reindex api to copy data(300K records), but it takes long time(several hours). any idea?

{
"source": {
"index": "trades",
"type": "trade",
"size": 1000
},
"dest": {
"index": "trades_day0",
"version_type": "internal"
}
}

Slow disk IO? 100% cpu utilization? Could just be a hardware bottleneck if the node is very small.

You could try slicing the reindex to speed it up, although I suspect it's a hardware issue.
