Michał PawlikowskiAzure, Azure Data Factory

Variability in Azure Data Factory pipeline run times and how Azure region load affects them?

Exporting data to PARQUET file and ADLS Gen2 using Azure Synapse Serverless

Exporting query data is quite simple as one-two-three: One: define your file format

1
2
CREATE EXTERNAL FILE FORMAT parquetfile1
WITH ( FORMAT_TYPE = PARQUET, DATA_COMPRESSION = 'org.apache.hadoop.io.compress.SnappyCodec' );

  Two: define your file location (note: you should have read/write/list permission the path)

1
2
CREATE EXTERNAL DATA SOURCE ADLS_DS
WITH( LOCATION = 'abfss://synapse@deltapoc0storage0dest.dfs.core.windows.net')

    Three: Create external table in particular location, using format and path from previous steps:
