Deleting records from Apache Hudi Table which is part of Glue Tables created using AWS Glue Job and Kinesis – Amazon Web Sevices

Setup overview

I currently have a DynamoDB stream configured which is inputing streams into Kinesis Data streams whenever insertion/updation happens and subsequently I have Glue tables which is taking input from above kinesis stream and then displaying the structural schema and also a Glue script is helping me create a Hudi Table which can be accessed using Athena. I’m currently able to monitor streaming data and able to see insertions/updations (simulating from boto3 using pycharm in my local machine) in my Athena table. Can we perform deletions aswell using the same Glue Job?

My Glue Script helping me create Glue Table (Hudi Table) looks as below –

import sys

        new_df = ApplyMapping.apply(frame = DataSource0, mappings=your_map, transformation_ctx = "applymapping1")
        abc = new_df.toDF()
        
        inputDf = abc.withColumn('update_ts_dms',to_timestamp(abc["registrationDate"])).withColumn('partitionkey',abc["id"].substr(-1,1)).withColumn('partitionkey2',abc["id"].substr(-2,1))
        
        

        # glueContext.write_dynamic_frame.from_options(frame = DynamicFrame.fromDF(inputDf, glueContext, "inputDf"), connection_type = "marketplace.spark", connection_options = combinedConf)
        glueContext.write_dynamic_frame.from_options(frame = DynamicFrame.fromDF(inputDf, glueContext, "inputDf"), connection_type = "custom.spark", connection_options = combinedConf)


glueContext.forEachBatch(frame = data_frame_DataSource0, batch_function = processBatch, options = {"windowSize": "10 seconds", "checkpointLocation":  s3_path_spark})


job.commit()

How do I implement deletion / script to reflect deletion changes in my dynamodb table in the same script? Is it even possible?

EDIT:

Added below lines to script. Resulting in deletion of all rows and empty table in Athena.

deleteDataConfig = {'hoodie.datasource.write.operation': 'delete'}


combinedConf = {**commonConfig, **partitionDataConfig, **incrementalConfig, **deleteDataConfig}

EDIT: Trying to add something like this in script after referring documentation of hudi


deleteConfig = {'hoodie.datasource.write.operation': 'delete', 'hoodie.delete.shuffle.parallelism': '1'}

Resulting in

    Was able to solve it by adding delete configs!


  2. 0

    Hudi can achieve deletes if the version is greater than 0.5.1

    df.write.format("org.apache.hudi").
options(getQuickstartWriteConfigs).
option(OPERATION_OPT_KEY,"delete").
option(PRECOMBINE_FIELD_OPT_KEY, "ts").
option(RECORDKEY_FIELD_OPT_KEY, "uuid").
option(PARTITIONPATH_FIELD_OPT_KEY, "partitionpath").
option(TABLE_NAME, tableName).
mode(Append).
save(basePath);
