Snap type: Write

Description:

This Snap executes a Redshift bulk load. The input data is first written to a staging file on S3. Then the Redshift copy command is used to insert data into the target table.

Table Creation

If the table does not exist when the Snap tries to do the load, and the Create table property is set, the table will be created with the columns and data types required to hold the values in the first input document. If you would like the table to be created with the same schema as a source table, you can connect the second output view of a Select Snap to the second input view of this Snap. The extra view in the Select and Bulk Load Snaps are used to pass metadata about the table, effectively allowing you to replicate a table from one database to another.

The table metadata document that is read in by the second input view contains a dump of the JDBC DatabaseMetaData class. The document can be manipulated to affect the CREATE TABLE statement that is generated by this Snap. For example, to rename the name column to full_name, you can use a Mapper (Data) Snap that sets the path "$.columns.name.COLUMN_NAME" to full_name. The document contains the following fields:

columns - Contains the result of the getColumns() method with each column as a separate field in the object. Changing the COLUMN_NAME value will change the name of the column in the created table. Note that if you change a column name, you do not need to change the name of the field in the row input documents. The Snap will automatically translate from the original name to the new name. For example, when changing from name to full_name, the name field in the input document will be put into the "full_name" column. You can also drop a column by setting the COLUMN_NAME value to null or the empty string. The other fields of interest in the column definition are:
- TYPE_NAME - The type to use for the column. If this type is not known to the database, the DATA_TYPE field will be used as a fallback. If you want to explicitly set a type for a column, set the DATA_TYPE field.
- _SL_PRECISION - Contains the result of the getPrecision() method. This field is used along with the _SL_SCALE field for setting the precision and scale of a DECIMAL or NUMERIC field.
- _SL_SCALE - Contains the result of the getScale() method. This field is used along with the _SL_PRECISION field for setting the precision and scale of a DECIMAL or NUMERIC field.
primaryKeyColumns - Contains the result of the getPrimaryKeys() method with each column as a separate field in the object.
declaration - Contains the result of the getTables() method for this table. The values in this object are just informational at the moment. The target table name is taken from the Snap property.
importedKeys - Contains the foreign key information from the getImportedKeys() method. The generated CREATE TABLE statement will include FOREIGN KEY constraints based on the contents of this object. Note that you will need to change the PKTABLE_NAME value if you changed the name of the referenced table when replicating it.
indexInfo - Contains the result of the getIndexInfo() method for this table with each index as a separated field in the object. Any UNIQUE indexes in here will be included in the CREATE TABLE statement generated by this Snap.

ETL Transformations & Data Flow

This Snap executes a Load function with the given properties. The documents that are provided on the input view will be inserted into the provided table on the provided database.

Input & Output:

Input: This Snap can have an upstream Snap that can pass a document output view. Such as Structure or JSON Generator.
Output: The Snap outputs one document specifying the status, with the records count that are being inserted into the table and also the failure record count. Any error occurring during the process is routed to the error view.
Expected Upstream Snaps: The columns of the selected table need to be mapped upstream using a Mapper Snap. The Mapper Snap will provide the target schema, which reflects the schema of the table that is selected for the Redshift Bulk Load Snap.
Expected Downstream Snaps: The Snap will output a single document for the entire bulk load operation which contains the count of records inserted into the targeted table as well as the count of failed records.

Prerequisites:

IAM Roles for Amazon EC2

The 'IAM_CREDENTIAL_FOR_S3' feature is used to access S3 files from EC2 Groundplex, without Access-key ID and Secret key in the AWS S3 account in the Snap. The IAM credential stored in the EC2 metadata is used to gain access rights to the S3 buckets. To enable this feature, the following line should be added to global.properties and the jcc (node) restarted:
jcc.jvm_options = -DIAM_CREDENTIAL_FOR_S3=TRUE

Please note this feature is supported in the EC2-type Groundplex only.

For more information on IAM Roles, see http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/iam-roles-for-amazon-ec2.html

Limitations and Known Issues

Does not work in Ultra Task Pipelines.
The Snap will not automatically fix some errors encountered during table creation since they may require user intervention to be resolved correctly. For example, if the source table contains a column with a type that does not have a direct mapping in the target database, the Snap will fail to execute. You will then need to add a Mapper (Data) Snap to change the metadata document to explicitly set the values needed to produce a valid CREATE TABLE statement.
If string values in the input document contain the '\0' character (string terminator), the Redshift COPY command, which is used by the Snap internally, fails to handle them properly. Therefore, the Snap skips the '\0' characters when it writes CSV data into the temporary S3 files before the COPY command is executed.

Account:

This Snap uses account references created on the Accounts page of SnapLogic Manager to handle access to this endpoint. The S3 Bucket, S3 Access-key ID and S3 Secret key properties are required for the Redshift-Bulk Load Snap. The S3 Folder property may be used for the staging file. If the S3 Folder property is left blank, the staging file will be stored in the bucket. See Configuring Redshift Accounts for information on setting up this type of account.

Configurations:

Account & Access

This Snap uses account references created on the Accounts page of SnapLogic Manager to handle access to this endpoint. The S3 Bucket, S3 Access-key ID and S3 Secret key properties are required for the Redshift-Bulk Load Snap. The S3 Folder property may be used for the staging file. If the S3 Folder property is left blank, the staging file will be stored in the bucket. See Configuring Redshift Accounts for information on setting up this type of account.

Views:

Input

This Snap has one document input view by default.

You can add a second view for metadata for the table as a document so that the target absent table can be created in the database with a similar schema as the source table. This schema is usually from the second output of a database Select Snap. If the schema is from a different database, the data types might not be properly handled.

Output

This Snap has at most one output view.

Error

This Snap has at most one error view and produces zero or more documents in the view. If you open an error view and expect to have all failed records routed to the error view, you must increase the Maximum error count property. If the number of failed records exceeds the Maximum error count, the pipeline execution will fail with an exception thrown and the failed records will not be routed to the error view.

Settings

Label*

Specify the name for the Snap. You can modify this to be more specific, especially if you have more than one of the same Snap in your pipeline.

Schema name

Specify the database schema name. In case it is not defined, then the suggestion for the Table Name will retrieve all tables names of all schemas. The property is suggestible and will retrieve available database schemas during suggest values.

The values can be passed using the pipeline parameters but not the upstream parameter.

Example: SYS
Default value: None

Table name*

Specify the table on which to execute the bulk load operation.

You can pass the values using the Pipeline parameters but not the upstream parameter.

Example: people

Default value: None

Create table if not present

Select this check box to automatically create the target table if it does not exist.

If a second input view is configured for the Snap and it contains a document with schema (metadata) of the source table, the Snap creates the new (target) table using the same schema (metadata). However, if the schema comes from a different database, the Snap might fail with Unable to create table: "<table_name>" error due to data type incompatibility.
In the absence of a second input view (the schema/metadata document), the Snap creates a table based on the data types of the columns generated from the first row of the input document (first input view).

Due to implementation details, a newly created table is not visible to subsequent database Snaps during runtime validation. If you wish to immediately use the newly updated data you must use a child Pipeline that is invoked through a Pipeline Execute Snap.

Default value: Not selected

Validate input data

Select this check box to enable the Snap perform input data validation to verify all input documents are flat map data. If any value is a Map or a List object, the Snap writes an error to the error view, and if this condition occurs, no document is written to the output view. See the Troubleshooting section above for information on handling errors caused due to invalid input data.

Default value: Not selected

Recommendation

If this property is not selected, the Snap does not validate the structure of input documents, converts all values to strings, writes the S3 CSV file, and executes the Redshift COPY command. If the COPY command finds error in the input CSV data, it writes errors to the error table, and the Snap routes these errors to the error view (if error view is enabled). However, some errors reported by the COPY command may not be easy to understand. Therefore, it is advisable to enable input data validation during pipeline development and testing, as this may also help troubleshoot the pipeline.

Flat Map Data

Flat map data is a collection of key-value pairs, where the values are all single-class objects unlike a Map or List.

Truncate data*

Select this check box to truncate existing data before performing data load. With the Bulk Update Snap, instead of doing truncate and then update, a Bulk Insert would be faster.

Default value: Not selected

Update statistics

Select this check box to update table statistics after data load by performing an Analyze operation on the table.

Default value: Not selected

Accept invalid chars

Select this check box to accept invalid characters in the input. Invalid UTF-8 characters are replaced with a question mark when loading.

Default value: Selected

Maximum error count*

Specify the maximum number of rows which can fail before the bulk load operation is stopped.

Default: 100
Example: 10 (if you want the Pipeline execution to continue as far as the number of failed records is less than 10)

Truncate columns

Select this check box to truncate column values which are larger than the maximum column length in the table

Default value: Selected

Disable data compression

Select this check box to disable compression of data being written to S3. Disabling compression will reduce CPU usage on the Snaplex machine, at the cost of increasing the size of data uploaded to S3.

Default value: Not selected

Load empty strings Select this check box to load empty strings in the input documents as empty strings to the string-type fields. Else, empty string values in the input documents are loaded as null. Null values are loaded as null regardless.

Default value: Not selected

Additional options

Specify additional options to be passed to the COPY command. Check Amazon Redshift – Copy for available options.

Default value: None

Parallelism

Define the number of files to be created in S3 per execution. If set to 1 then only one file will be created in S3 which will be used for the copy command. If set to n with n > 1, then n files will be created as part of a manifest copy command, allowing a concurrent copy as part of the Redshift load. The Snap itself will not stream concurrent to S3. It will use a round robin mechanism on the incoming documents to populate the n files. The order of the records is not preserved during the load.

Default value: None

IAM Role Select this check box if bulk load or unload has to be done using the IAM role. If you select IAM Role, ensure that you provide values for (AWS account ID, Role name, and Region name) fields in the Redshift Account.

Server-side encryption

Select this check box to enable encryption for the data that is loaded. This defines the S3 encryption type to use when temporarily uploading the documents to S3 before you insert data into Redshift.

Default value: Not selected

KMS Encryption type

Specify the type of Key Management Service (KMS) S3 encryption to be used on the data. The available encryption options are:

None - Files do not get encrypted using KMS encryption
Server-Side KMS Encryption - This option enables the output files on Amazon S3 to be encrypted using the Amazon S3 generated KMS key.

Default value: None

If both the KMS and Client-side encryption types are selected, the Snap gives precedence to the SSE, and displays an error prompting the user to select either of the options only.

KMS key

Activates when KMS Encryption type is set to Server-Side Encryption with KMS.

Specify the KMS key to use for the S3 encryption. For more information about the KMS key, refer to AWS KMS Overview and Using Server Side Encryption.

Default value: None

Vacuum type

Select the option for Vacuum type.

Vacuum type reclaims space and sorts rows in a specified table after the upsert operation. The available options to activate are FULL, SORT ONLY, DELETE ONLY and REINDEX. Refer to the AWS document on Vacuuming Tables for more information.

Auto-commit needs to be enabled for Vacuum.

Default value: None

Vacuum threshold (%)

Specifies the threshold above which VACUUM skips the sort phase. If this property is left empty, Redshift sets it to 95% by default.

Default value: None

Snap execution

Select one of the three modes in which the Snap executes. Available options are:

Validate & Execute: Performs limited execution of the Snap, and generates a data preview during Pipeline validation. Subsequently, performs full execution of the Snap (unlimited records) during Pipeline runtime.
Execute only: Performs full execution of the Snap during Pipeline execution without generating preview data.
Disabled: Disables the Snap and all Snaps that are downstream from it.

In a scenario where the Auto commit on the account is set to true, and the downstream Snap does depends on the data processed on an Upstream Database Bulk Load Snap, use the Script Snap to add delay for the data to be available.

For example, when performing a create, insert and a delete function sequentially on a pipeline, using a Script Snap helps in creating a delay between the insert and delete function or otherwise it may turn out that the delete function is triggered even before inserting the records on the table.

Redshift's Vacuum Command

In Redshift, when rows are DELETED or UPDATED against a table they are simply logically deleted (flagged for deletion), not physically removed from disk. This causes the rows to continue consuming disk space and those blocks are scanned when a query scans the table. This results in an increase in table storage space and degraded performance due to otherwise avoidable disk IO during scans. A vacuum recovers the space from deleted rows and restores the sort order.

Basic Use Case

The following Pipeline describes how the Snap functions as a standalone Snap in a Pipeline:

Use Case: Replicate a Database Schema in Redshift

MySQL Select to Redshift Bulk Load
In this example, a MySQL Select Snap is used to select data from 'AV_Persons' table belonging to the 'enron' schema. The Mapper Snap maps this data to the target table's schema and is then loaded onto the "bulkload_demo" table in the "prasanna" schema:

Select the data from the MySQL database.

Mapper will be used to map the data to the input schema that is associated with Redshift Bulkload database table.

Loads the input Documents that is coming from the Mapper to a S3 file.

Finally invoke the COPY command to invoke the created S3 file to insert the data into the destination table.

Typical Snap Configurations

Key configuration lies in how the SQL statements are passed to perform bulk load of the records. The statements can be passed:

Without Expression

The values are passed directly to the Snap.

With Expression

Using Pipeline parameters
The Table name is passed as a Pipeline parameter.

Basic Use Case #2: Use of twin inputs to define schema while creating tables in Redshift

The following Pipeline demonstrates how to use the second input view of Redshift - Bulk Load Snap to define the schema for creating a non-existent table in Redshift data store.

We use two JSON Generator Snaps: one for passing the table schema and another for passing the data rows.

Input 1: Schema	Input 2: Data

We use the Redshift Bulk Upload Snap to combine these two inputs — schema and data rows, and create a table, if it does not exist in the Redshift Data store.

Redshift - Bulk Load Snap Settings	Views

Output

After creating the table and loading the data based on these inputs, the Snap displays the result in the output in terms of the number of records loaded into the specified table and the number of failed records.

To see the records inserted into the new table, we can connect a Redshift - Execute Snap and run a select query on the newly-created table. It retrieves the data inserted into each record. It is possible that you see more records in the output, in case the table existed and the new rows are inserted into it.

Advanced Use Case

The following Pipeline describes how a lookup functionality is used in an enterprise environment. In this Pipeline, tweets pertaining to a keyword "#ThursdayThoughts" are extracted using a Twitter Query Snap and loaded into the table "twittersnaplogic" in the public schema using the Redshift Bulk Load Snap. When executed, all the records are loaded into the table.

The Pipeline performs the following ETL operations:

Extract: Twitter Query Snap selects 25 tweets (a value specified in the Maximum tweets property) pertaining to the Twitter query.

Transform: The Sort Snap, labeled Sort by Username in this pipeline, sorts the records based on the value of the field user.name.

Extract: The Salesforce SOQL Snap extract's records matching the user.name field value. Extracted records are LastName, FirstName, Salutation, Name, and Email.

Load: The Redshift Bulk Load Snap loads the results into the table, twittersnaplogic, on the Redshift instance.

The configuration of the Twitter Query Snap is as shown below:

The Twitter Query Snap is configured to retrieve 25 records from the Account, a preview of the Snap's operation is shown below:

The Redshift Bulk Load Snap is configured as shown in the figure below:

Successful execution of the Snap is denoted by a count of the records loaded into the specified table, note that the number of failed records is also shown provided it does not exceed the limit specified in the Maximum error count property, in which case it would stop the pipeline. The image below shows that all 25 records retrieved in the Twitter Query Snap have been loaded into the table successfully.

Advanced Use Case #2

The following Pipeline demonstrates how a bulk load functionality is used typically in an enterprise environment. In this Pipeline, the File Reader Snap reads the data, from which the data will be loaded in to the table using the Redshift Bulk Load Snap. When executed, all the records are loaded into the table.

The Pipeline performs the following ETL operations:

Extract: File Reader snap will read the data from the file and submit it to the CSV parser.

Transform: CSV Parser will perform the parsing of the provided data which will be written to the MySQL insert snap.

Extract: The entire data will be loaded into the Redshift table, by creating new table with the provided schema.
