Geo Bounds Aggregation
The geo-bounds aggregation computes the bounding box containing all geo-points in the field. Let’s calculate the geo-bounds for a field containing geo points.
Query
GET /locations/_search
{
"size": 0,
"aggs": {
"geo_bounds": {
"geo_bounds": {
"field": "location"
}
}
}
}
Output
{
"aggregations": {
"geo_bounds": {
"bounds": {
"top_left": {
"lat": 40.73,
"lon": -74.1
},
"bottom_right": {
"lat": 40.01,
"lon": -71.12
}
}
}
}
}
In this example, the geo-bounds aggregation calculates the bounding box for the geo-points.
Metric Aggregation in Elasticsearch
Elasticsearch is a powerful tool not just for search but also for performing complex data analytics. Metric aggregations are a crucial aspect of this capability, allowing users to compute metrics like averages, sums, and more on numeric fields within their data.
This guide will delve into metric aggregations in Elasticsearch, explaining what they are, how they work, and providing detailed examples to illustrate their use.
