Transforming time series data points from concurrent processes is described. A time series database system writes, to a queue, a first time series data point received from a first process. The time series database system writes, to the queue, a second time series data point received from a second process that executes concurrently with the first process. The time series database system removes the first time series data point and the second time series data point from the queue. The time series database system creates transformed time series data by applying a transformation to the first time series data point and the second time series data point. The time series database system outputs the transformed time series data to a user device.
