You could use standard stuff from java.util.concurrent: import java.util.concurrent._ val ex = new ScheduledThreadPoolExecutor(1) val task = new Runnable { def run() = println(“Beep!”) } val f = ex.scheduleAtFixedRate(task, 1, 1, TimeUnit.SECONDS) f.cancel(false) Or java.util.Timer: val t = new java.util.Timer() val task = new java.util.TimerTask { def run() = println(“Beep!”) } t.schedule(task, 1000L, 1000L) task.cancel()

How to join two dataframes for which column values are within a certain range?

by

One simple solution is create interval index from start and end setting closed = both then use get_loc to get the event i.e (Hope all the date times are in timestamps dtype ) df_2.index = pd.IntervalIndex.from_arrays(df_2[‘start’],df_2[‘end’],closed=’both’) df_1[‘event’] = df_1[‘timestamp’].apply(lambda x : df_2.iloc[df_2.index.get_loc(x)][‘event’]) Output : timestamp A B event 0 2016-05-14 10:54:33 0.020228 0.026572 E1 1 … Read more

Using a variable period in an interval in Postgres

by

Use this line: startDate TIMESTAMP := endDate – ($3 || ‘ MONTH’)::INTERVAL; and note the space before MONTH. Basically: You construct a string with like 4 MONTH and cast it with ::type into a proper interval. Edit: I’ have found another solution: You can calculate with interval like this: startDate TIMESTAMP := endDate – $3 … Read more
