Managing Tables Using the IntelliJ Plugin

Learn how to create tables and view table data in Oracle NoSQL Database Cloud Service or Oracle NoSQL Database Cloud Simulator from IntelliJ.

After connecting to the Oracle NoSQL Database Cloud Simulator or Oracle NoSQL Database Cloud Service, you can execute the examples downloaded with Oracle NoSQL Database Java SDK to create a sample table. With the help of the IntelliJ Plugin, you can view the tables and their data in the Schema Explorer window.
Execute an example program:
  1. Open the NoSQL project connected to your Oracle NoSQL Database Cloud Service or simulator.
  2. Locate and click BasicTableExample in the Project Explorer window. You will find this in the examples folder under oracle-nosql-java-sdk. By looking at the code, you can notice that this program creates a table called audienceData, puts two rows into this table, queries the inserted rows, deletes the inserted rows, and finally drops the audienceData table.
  3. To pass the required arguments, click Run > Edit Configurations. Depending on the connection type, enter the following program arguments, and click OK.

    Table - Program Arguments

    Connection Type Program Arguments More Information
    Cloudsim http://localhost:8080 If you started the Oracle NoSQL Database Cloud Simulator on a different port, you must replace 8080 with that port number.
    Cloud us-ashburn-1 -configFile D:\OCI_PROP\config The first argument indicates the data region of your Oracle NoSQL Database Cloud Service. The second argument passes a configuration file that contains the credentials to connect to the Oracle NoSQL Database Cloud Service.
  4. To execute this program, click Run > Run 'BasicExampleTable' or press Shift + 10.
  5. Verify the logs in the terminal to confirm that the code executed successfully. You can see the display messages that indicate table creation, rows insertion, and so on.

    Tip:

    As the BasicExampleTable deletes the inserted rows and drops the audienceData table, you can't view this table in the Schema Explorer. If you want to see the table in the Schema Explorer, comment the code that deletes the inserted rows and drops the table, and rerun the program.
  6. To view the tables and their data:
    1. Locate the Schema Explorer, and click the Refresh icon icon to reload the schema.
    2. Locate the audienceData table under your tenant identifier, and expand it to view its columns, primary key, and shard key details.
    3. Double-click the table name to view its data. Alternatively, you can right-click the table and select Browse Table.
    4. A record viewer window appears in the main editor. Click Execute to run the query and display table data.
    5. To view individual cell data separately, double-click the cell.

Freeze/UnFreeze Schema

You need to freeze the schema of a singleton table before making it a Global Active table. Once you freeze the schema of the table, you cannot make any changes to the schema. To freeze the schema of a singleton table, it should have at least one JSON column. Right-click on the table and choose Freeze/Unfreeze. Once you confirm, the schema of the table gets frozen. Similarly, to unfreeze the schema of the table, right-click on the table and choose Freeze/Unfreeze. Once you confirm, the schema of the table is changed back to mutable which means the schema can be altered.

Note:

The table regional replicas need to be dropped (the table must be a singleton table) before the unfreeze operation can be performed.

Manage Replicas

See Regional Table Replicas to understand what are replicas and how to convert a singleton table to a Global active table by adding regional replicas.

Add Replica

You can add a regional replica to a singleton table, to make it a Global active table or add a replica to an existing Global active table. The table should be frozen before you add a replica to it. Right-click on the table and choose Add Replica from Regional Replicas. You can choose a replica from the dropdown of the Replication region. You can decide on the Read Units and Write Units of the table in that replication region. The Disk Storage value for the table cannot be changed/edited in the replica. Click Add Replica. The table gets replicated in the region.

View Replica

Right-click on the table and choose View Replicas from Regional Replicas. You can view the list of replicas for the table.

Drop Replicas

Right-click on the table and choose Drop Replicas from Regional Replicas. Click Add and choose a replica to be removed. You can choose more than one replica to be dropped at a single time. Click Remove if you want to remove the replica from the list of replicas that need to be dropped. Click Drop Replicas. Once you confirm, the table is dropped from all the selected replicas.

Edit Reserved Capacity

You can edit the reserved capacity and the usage model of a table. Right-click on the table and choose Edit Reserved Capacity. You can choose one of the two capacity modes - Provisioned capacity or On-demand capacity. Edit the values and click Apply Changes.

If the table that is edited is a Global Active table:
  • Change in storage capacity has a global scope (change in one regional table replica is automatically propagated to all regional table replicas).
  • Change in read units, write units or change in capacity mode from On-Demand to provisioned or vice-versa has a local scope (change only in the regional table replica where it is initiated).
