Converting timestamp format in dataframe

发布于 2020-12-02 13:27:59

I have read a csv file and made a dataframe where timestamp column is in format "11/12/2020 3:01".

How do I convert this into "yyyy-mm-dd hh:mm:ss.ssssss" format for the data of that particular timestamp column?

import org.apache.spark.sql.functions._

df.withColumn("timestamp_col",
    date_format(
        unix_timestamp($"timestamp_col", "dd/MM/yyyy h:mm").cast("timestamp"),  
        "yyyy-MM-dd hh:mm:ss.SSSSSS"
    )
)

Mamba is a new state space model architecture showing promising performance on information-dense data such as language modeling, where previous subquadratic models fall short of Transformers. It is based on the line of progress on structured state space models, with an efficient hardware-aware design and implementation in the spirit of FlashAttention.
