Method Detail

setDynamoDbProperties

public DynamoDbSinkBuilder<InputT> setDynamoDbProperties(Properties properties)

setElementConverter

public DynamoDbSinkBuilder<InputT> setElementConverter(org.apache.flink.connector.base.sink.writer.ElementConverter<InputT,DynamoDbWriteRequest> elementConverter)

setTableName

public DynamoDbSinkBuilder<InputT> setTableName(String tableName)

Table name for the DynamoDB sink.

setOverwriteByPartitionKeys

public DynamoDbSinkBuilder<InputT> setOverwriteByPartitionKeys(List<String> overwriteByPartitionKeys)

Parameters:

overwriteByPartitionKeys - list of attribute key names for the sink to deduplicate on if you want to bypass the no duplication limitation of a single batch write request. Batching DynamoDB sink will drop request items in the buffer if their primary keys(composite) values are the same as the newly added ones. The newer request item in a single batch takes precedence.

setFailOnError

public DynamoDbSinkBuilder<InputT> setFailOnError(boolean failOnError)

setMaxBatchSizeInBytes

public DynamoDbSinkBuilder<InputT> setMaxBatchSizeInBytes(long maxBatchSizeInBytes)

Overrides:

setMaxBatchSizeInBytes in class org.apache.flink.connector.base.sink.AsyncSinkBaseBuilder<InputT,DynamoDbWriteRequest,DynamoDbSinkBuilder<InputT>>

setMaxRecordSizeInBytes

public DynamoDbSinkBuilder<InputT> setMaxRecordSizeInBytes(long maxRecordSizeInBytes)

Overrides:

setMaxRecordSizeInBytes in class org.apache.flink.connector.base.sink.AsyncSinkBaseBuilder<InputT,DynamoDbWriteRequest,DynamoDbSinkBuilder<InputT>>

build

public DynamoDbSink<InputT> build()
