Hi Team,
Currently I am running elasticsearch with three nodes. Couple of days back I upgraded elasticsearch from 2.1.1 to 2.2.0. In one of the index I have around 52 million records and I am running a simple query to get the first inserted record using the time field which is in epoch time format.
Below is the query
{
"size": 0,
"filter": {
"query": {
"range": {
"time": {
"from": "now-1d",
"to": "now"
}
}
}
},
"aggs": {
"min_time": {
"min": {
"field": "time"
}
}
}
}
Now this simple query is taking like 8 min to return min value. Before upgrading to was comparatively fast. Is this a know issue?
Thanks,
