I have been trying to use autoloader with foreach so that I could able to use merge into in databricks, but while using I have been getting below error.
from delta.tables import *
streaming_df=(spark.readStream.format("cloudFiles")
.option("cloudFiles.format", "parquet")
.option("cloudFiles.schemaLocation", f"{output_path}/schemalocation")
.load(f"{input_path}"))
deltaTable = DeltaTable.forName(spark,"vyxdbsucdev.silver_generalledger_erpcloud_gl.journalline")
# Function to upsert microBatchOutputDF into Delta table using merge
def upsertToDelta(microBatchOutputDF, batchId😞
(deltaTable.alias("t").merge(
microBatchOutputDF.alias("s"),
"s.JeHeaderId = t.JeHeaderId" and "s.JeLineId = t.JeLineId")
.whenMatchedUpdateAll()
.whenNotMatchedInsertAll()
.execute()
)
# Write the output of a streaming aggregation query into Delta table
query=(streaming_df.writeStream
.foreachBatch(upsertToDelta)
.outputMode("update")
.start()
)
Complete error:
