  • What happens to my data if I decide I no longer want to use the NoSQL Database?

    Upon termination of your subscription, you will have 60 days to transfer your data for the terminated service from Oracle Cloud to a local system. After 60 days, Oracle permanently deletes any remaining content and software related to the terminated service.

  • Is my data safe if there is an issue with a data center?

    Oracle NoSQL Database stores multiple copies of the data across availability domains for redundancy. If one availability domain (within a region) goes down, the data is still available to the application from the other availability domains.

  • What if the client application goes down?

    It is the responsibility of the owner of the application to implement a strategy that will ensure that the application remains active.

  • Which Oracle Cloud Infrastructure sites will Oracle NoSQL Database be available in?
  • Can an application request cross-regional replication for Oracle NoSQL Database data?

    Data is only replicated across availability domains within a region, not across regions.

  • Is my data encrypted on disk (“encrypted at rest”) and what type of encryption?

    Yes. Data is encrypted at rest with Advanced Encryption Standard (AES 256).

  • Is my data encrypted between my application and Oracle NoSQL Database?

    Yes. Data is encrypted in motion (transferring data between the application and Oracle NoSQL Database Cloud Service) with HTTPS.

  • What servers do I need to purchase for my application to run on?

    The application should run in Oracle Cloud Infrastructure. There are different instance shapes available for your application depending on its complexity and the workloads. A list of different shapes can be found on the Oracle Cloud Infrastructure web page.

  • How do I get started with Oracle NoSQL Database?
  • Where can I run the application that connects to Oracle NoSQL Database?

    It is advisable to run the application using Oracle Cloud infrastructure for the best user and customer experience.

  • What software do I need to install on the client server?

    Software development kits (SDKs) are available for the following programming languages. Follow the steps on download and installation in the links below.

    More SDKs will be available in the future.

  • What are the Oracle NoSQL Database data models?

    Columnar, Key-Value, and Document.

  • What happens if my throughput exceeds my provisioned limit?

    If the provisioned throughput limits are exceeded on read/write operations, Oracle NoSQL Database will throttle the requests and throw a ThrottlingException error to the application. The provisioned throughput limits can be increased if needed.

  • What latencies can I expect for my operations?

    Predictable sub-10 milliseconds latency for database operations.

  • Does Oracle NoSQL Database support ACID transactions?

    Yes. Oracle NoSQL Database provides ACID compliant transactions for full create, read, update, and delete (CRUD) operations, with adjustable durability and consistency transaction guarantees.

  • Can I develop an Oracle NoSQL Database application without purchasing the service?

    Yes. You can use Oracle NoSQL Cloud Simulator which is a standalone, local copy of the cloud service. It can be used for testing. It is not intended for production deployment. You can download it from the Oracle Cloud Downloads page.

  • How to I provide feedback or report issues with the Oracle NoSQL Java SDK?

    Send email to: oraclenosql-info_ww@oracle.com, or contact us through https://cloudcustomerconnect.oracle.com/pages/home. We monitor both regularly.

  • How can I move data that I have stored in my on-premise Oracle NoSQL Database implementation to Oracle NoSQL Database?

    You can upload data to Oracle Cloud Infrastructure Object Storage, and have your application read from Oracle Cloud Infrastructure Object Storage, then write to Oracle NoSQL Database.

  • Are there REST services available for Oracle NoSQL Database?

    Yes.

  • What are the Read and Write Capacity Units?

    Read Unit per Month is defined as the throughput of up to one kilobyte (KB) of data per second for an eventually consistent read operation (i.e., where the data returned may not be the most recently written data to the database; if no new updates are made to the data, eventually all accesses to that data will return the latest updated value) over a one-month period, or approximately two million six hundred thousand (2.6 million) reads. Each month is deemed to have seven hundred forty-four (744) hours or approximately two million six hundred thousand (2.6 million) seconds. So over a one-month period, one (1) read unit will provide you with approximately 2.6 million reads. To achieve the throughput of up to one kilobyte (KB) of data per second for an absolute consistent read operation (i.e., where the data returned is expected to be the most recently written data to the database), the equivalent of two read units per month need to be provisioned.

    Write Unit per Month: is defined as the throughput of up to one kilobyte (KB) of data per second for a write operation over a one month period, or approximately two million six hundred thousand (2.6 million) writes. Each month is deemed to have seven hundred forty-four (744) hours or approximately two million six hundred thousand (2.6 million) seconds. So over a one-month period, one (1) write unit will provide you with approximately 2.6 million writes.

  • How do I determine the size of an item?

    Please refer to the white paper: Oracle NoSQL Database Capacity Planning (PDF).

  • What will be the cost?
  • How to estimate read and write capacity units?

    Please refer to the white paper: Oracle NoSQL Database Capacity Planning (PDF).

  • Can I change what I provision for the number of read units, number of write units or the amount of storage?

    Yes. Your application can change the provisioned number of read units, write unites or storage capacity through the TableLimits API.

    You can also change the provisioned number of read units, write units, or storage capacity using the service UI.

  • How do I determine the amount for each read or write unit that I am planning?

    Determine the size in bytes and round up to the next KB.

  • If I am not using all of my provisioned read or write units, do I still get charged?

    Yes. Since the throughput can be scaled up or down programmatically at any time, make sure to provision the throughput accordingly for the workloads.

  • Is there a way to estimate my monthly bill?

    Yes. Please refer to the online calculator at: https://www.oracle.com/cloud/cost-estimator.html. Select Data Management, then select Oracle NoSQL Database Cloud.

  • What is the maximum storage per tenant?

    5 terabytes (TB) per tenant. This is the sum of all storage capacities of the tables provisioned within a tenancy . If you need more, contact Oracle.

  • What is the maximum throughput that can be provisioned for writing or reading for a single table?

    Oracle NoSQL Database is subject to the following usage limits. A tenant may create multiple tables up to these limits.

    Per Table Limits

    • The maximum number of write units that can be provisioned per table is 20,000 per second
    • The maximum number of read units that can be provisioned per table is 50,000 per second

    Per Tenant Limits

    • The maximum number of write units that can be provisioned per tenant is 40,000 per second
    • The maximum number of read units that can be provisioned per tenant is 100,000 per second
    • The maximum amount of storage per tenant is 5 terabytes (TB).

    Customers to contact Oracle if they need more write/read units or storage above the maximum usage limits.

  • Is there a limit on how many tables I can provision?

    The maximum number of tables per tenant is 30. For more information on limits, refer to https://docs.oracle.com/en/cloud/paas/nosql-cloud/csnsd/cloud-limits.html.
