# PYTHON
# connect to db using wrapper around psycopg2
db = DatabaseConnection(db='db', user='username', password='password')
# grab data from db and load into memory
df = db.run_query("SELECT * FROM cleaned_table;")
df = pd.DataFrame(df, columns=['user_id', 'series_id', 'timestamp'])
# calculate time since first visit
df = df.assign(time_since_first=df.groupby('user_id', sort=False).timestamp.apply(lambda x: x -
x.min()))
# calculate time since last visit
df = df.assign(time_since_last=df.sort_values(['timestamp'], ascending=True).groupby('user_id',
sort=False)['timestamp'].transform(pd.Series.diff))
# save df to compressed csv
df.to_csv('transform_time_test.gz', compression='gzip')
-- SQL equivalent
-- increase the working memory (be careful with this)
set work_mem='600MB';
-- create a dual index on the partition
CREATE INDEX IF NOT EXISTS user_time_index ON table(user_id, timestamp);
-- calculate time since last visit and time since first visit in one pass
SELECT *, AGE(timestamp, LAG(timestamp, 1, timestamp) OVER w) AS time_since_last, AGE(timestamp,
FIRST_VALUE(timestamp) OVER w) AS time_since_first FROM table WINDOW w AS (PARTITION BY user_id
ORDER BY timestamp);
SQL has taken over as dominant transformation tool
