Field / Field set Type Description
Label String

Required. Specify a unique label for the account.

Default value: N/A

Example: Cassandra SSL/TLS Database Account
Account properties Required. This fieldset allows you to enter in the information to create a connection to the database.

This fieldset comprises the following fields:

  • Hostname
  • Port Number
  • Database Name
  • KeyStore
  • TrustStore
  • KeyStore Password
  • TrustStore Password
  • Key Alias
  • Key Passphrase
Hostname String/Expression Required. The server's address to connect to.

You may want to provide multiple hostnames when using a Cassandra cluster. To do so, separate each hostname with two uninterrupted hyphens; for example, host1--host2--host3.

Warning:

The multiple hostnames support is not applicable for IP addresses.

Default value: None.
Port Number String/Expression Required. The database server's port to connect to.

Default value: 9042
Database name String/Expression Required. The database name to connect to.

Default value: None.
KeyStore String/Expression Required. The location of the key store file. It can be located in SLDB or any other unauthenticated endpoint such as 'https://'. You can also browse for the location.
TrustStore String/Expression Required. The location of the trust store file. It can be located in SLDB or any other unauthenticated endpoint such as 'https://'. You can also browse for the location.
KeyStore Password String/Expression Required. Password for the keystore file. Also used for TrustStore when TrustStore Password is not provided.
TrustStore Password String/Expression Password for the truststore file. Also used for KeyStore when KeyStore Password is not provided.
Key Alias String/Expression Alias of the private key to be used from the key store.
Key Passphrase String/Expression Password for the private key to be used from the key store.
Advanced properties
Use this fieldset to define specific settings. This fieldset comprises the following fields:
  • Auto commit
  • Batch Size
  • Fetch Size
  • Max Pool Size
  • Max Life Time
  • Idle Timeout
  • Check Timeout
Auto commit Checkbox/Expression

When selected, each of the batches is committed immediately after it is executed. If the Snap fails, only the batch being executed at that moment is rolled back.

When deselected, the Snap execution output is committed only after all the batches are executed. If the Snap fails, the entire transaction is rolled back, unless the Snap finds invalid input data before it sends the insert request to the server, and routes the error documents to the Error view.

Default status: Selected
Batch size Integer/Expression Required. Number of statements to execute at a time.
Warning: Select queries are not batched.
Warning: Using a large batch size could use up the JDBC placeholder limit of 2100.

Default value: 50
Fetch size Integer/Expression Required. Number of rows to fetch at a time when executing a query.
Warning: Large values could cause the server to run out of memory.

Default value: 100
Min pool size Integer/Expression Required. Minimum number of connections a pool will maintain at a time.

Default value: 3
Max pool size Integer/Expression Required. Maximum number of connections a pool will maintain at a time.

Default value: 50
Max life time Integer/Expression Required. Maximum lifetime of a connection in the pool. Ensure that the value you enter is a few seconds shorter than any database or infrastructure-imposed connection time limit.
Warning: A value of 0 indicates an infinite lifetime, subject to the Idle Timeout value. An in-use connection is never retired. Connections are removed only after they are closed.

Default value: 30
Idle Timeout Integer/Expression Required. The maximum amount of time a connection is allowed to sit idle in the pool.
Warning: A value of 0 indicates that idle connections are never removed from the pool.

Default value: 5
Checkout timeout Integer/Expression Required. Number of milliseconds to wait for a connection to be available when the pool is exhausted.
Note: If you specify 0, the Snap waits infinitely until the connection is available. Therefore, we recommend you not to specify 0 for Checkout Timeout.

Default value: 10000
URL Properties Use this fieldset to define URL properties.
URL property name String/Expression URL property name.

Default value: None.
URL property value String/Expression URL property value.

Default value: None.
With Execute Snaps

For a DB Execute Snap, assume that a stream of documents enters the input view of the Snap and the SQL statement property has JSON paths in the WHERE clause. If the number of documents are large, the Snap executes in more than one batches rather than executing one per each document. Each batch would contain a certain number of WHERE clause values. If Auto commit is turned on, a failure would only roll back the records in the current batch. If Auto commit is turned off, the entire operation would be rolled back. For a single execute statement (with no input view), the setting has no practical effect.
