Df = spark.read.format(delta).load('/whatever/path') df2 = df.filter(year = '2021' and month = '01' and day in ('04','05','06')) Df = spark.read.format (delta).load ('/mnt/raw/mytable/') df = df.filter (col ('ingestdate')=='20210703') many thanks in advance. Is there a way to optimize the read as dataframe, given: Web i am trying to load data from delta into a pyspark dataframe. Web is used a little py spark code to create a delta table in a synapse notebook. 2 timestampasof will work as a parameter in sparkr::read.df. Web 2 answers sorted by: Web read a table. Web option 1 : Df = spark.read.format (delta).option ('basepath','/mnt/raw/mytable/')\.load ('/mnt/raw/mytable/ingestdate=20210703') (is the basepath option needed here ?) option 2 :
It provides code snippets that show how to read from and write to delta tables from interactive, batch, and streaming queries. Web read a delta lake table on some file system and return a dataframe. Df = spark.read.format (delta).option ('basepath','/mnt/raw/mytable/')\.load ('/mnt/raw/mytable/ingestdate=20210703') (is the basepath option needed here ?) option 2 : Python people_df = spark.read.table(table_name) display(people_df) ## or people_df = spark.read.load(table_path) display(people_df) r people_df = tabletodf(table_name) display(people_df) scala Web seems the better way to read partitioned delta tables is to apply a filter on the partitions: Load (/tmp/delta/people10m) // create table by path import io. Web option 1 : Df = spark.read.format (delta).load ('/mnt/raw/mytable/') df = df.filter (col ('ingestdate')=='20210703') many thanks in advance. Web i am trying to load data from delta into a pyspark dataframe. Web instead of load function, you need to use table function: Web 2 answers sorted by:
