Elasticsearch Find Out does user stops or moving - Possible? - ruby-on-rails

Question

I want to use elasticsearch configuration about mapping to display user location and his/her direction to admin in my web app. so I create an index in elasticsearch like:
{
"settings": {
"index": {
"number_of_shards": 5,
"number_of_replicas": 1
},
"analysis": {
"analyzer": {
"analyzer-name": {
"type": "custom",
"tokenizer": "keyword",
"filter": "lowercase"
}
}
}
},
"mappings": {
"properties": {
"driver_id": { "type": "integer" },
"email": { "type": "text" },
"location": { "type": "geo_point" },
"app-platform": { "type": "text" },
"app-version": { "type": "text" },
"created_at": { "type": "date", "format": "yyyy-MM-dd HH:mm:ss||yyyy-MM-dd||epoch_millis"}
}
}
}
and start to inserting user location to elasticsearch with this curl
{
"driver_id": 357,
"driver_email": "Andrew#mailinatior.com",
"location": {
"lat": 37.3,
"lon": 59.52
},
"created_at": "2021-06-04 00:09:00"
}
this structure came from user mobile to my elasticsearch, after that I wrote these services to fetch data for my web-end part of my designing:
module Api
module V1
module Drivers
module Elastic
class LiveLocation
include Peafowl
attribute :driver_id, ::Integer
def call
#driver = ::Driver.find(driver_id) if driver_id.present?
result = []
options = {
headers: {
'Content-Type' => 'application/json'
},
body: #driver.present? ? options_with_driver : options
}
begin
response = HTTParty.get(elasticseach_url.to_s, options)
records = JSON.parse(response.body)['hits']['hits']
if records.present?
records.group_by { |r| r['_source']['driver_id'] }.to_a.each do |record|
driver = ::Driver.where(id: record[0]).first
if driver.present?
location = record[1][0]['_source']['location']
app_platform = record[1][0]['_source']['app-platform']
app_version = record[1][0]['_source']['app-version']
result.push(driver_id: driver.id, driver_email: driver.profile.email, location: location, app_platform: app_platform, app_version: app_version)
end
end
end
rescue StandardError => error
Rails.logger.info "Error => #{error}"
result = []
end
context[:response] = result
end
def elasticseach_url
"#{ENV.fetch('ELASTICSEARCH_BASE_URL', 'http://127.0.0.1:9200')}/#{ENV.fetch('ELASTICSEARCH_DRIVER_POSITION_INDEX', 'live_location')}/_search"
end
def options
{
query: {
bool: {
filter: [
{
range: {
created_at: {
gte: (Time.now.beginning_of_day.strftime '%Y-%m-%d %H:%M:%S')
}
}
}
]
}
},
sort: [
{
created_at: {
order: 'desc'
}
}
]
}.to_json
end
def optinos_with_driver
{
query: {
bool: {
must: [
{
term: {
driver_id: {
value: #driver.id
}
}
}
],
filter: [
{
range: {
created_at: {
gte: (Time.now.beginning_of_day.strftime '%Y-%m-%d %H:%M:%S')
}
}
}
]
}
},
sort: [
{
created_at: {
order: 'desc'
}
}
]
}.to_json
end
end
end
end
end
end
this structure working perfectly but even if the user stops while elasticsearch saves his location but I need to filter user data that if the user stops for one hour in place elasticsearch understand and not saving data. Is it possible?
I use elsticsearch 7.1
and ruby 2.5
I know it's possible in kibana but I could not using kibana at this tim.

Answer 1

I am not sure if this can be done via a single ES query...
However you can use 2 queries:
one to check if the user's location's during the last hour is the same
Second same then don't insert
But i don't recommend that
What you could do:
Use REDIS or any in-mem cache to maintain the user's last geo-location duration
Basis that, update or skip update to Elastic Search
PS: I am not familiar with ES geo-location API
