This project implements REST API to aggregate in memory statistics for last time window about real time transactions.
{
"amount": 12.3,
"timestamp": 1478192204000
}Where:
- amount - transaction amount
- timestamp - transaction time in epoch in millis in UTC time zone (this is not current timestamp) Returns: Empty body with either 201 or 204.
- 201 - in case of success
- 204 - if transaction is older than 60 seconds
Returns:
{
"sum": 1000,
"avg": 100,
"max": 200,
"min": 50,
"count": 10
}Where:
- sum is a double specifying the total sum of transaction value in the last 60 seconds
- avg is a double specifying the average amount of transaction value in the last 60 seconds
- max is a double specifying single highest transaction value in the last 60 seconds
- min is a double specifying single lowest transaction value in the last 60 seconds
- count is a long specifying the total number of transactions happened in the last 60 seconds
