Important

New database features are no longer connected to engine versions; features are now enabled independently during scheduled update windows, and “major” and “minor” releases no longer exist in Helios. Please visit the release notes to view the latest features available in your database clusters.

Best Practices

Here are some best practices to manage performance tradeoffs between transactions and analytics using SingleStore Kai.

Create Indexes

To improve query performance, SingleStore recommends creating indexes on the collections. Refer to Understanding Keys and Indexes in SingleStore for more information.

Faster Transactions (But Lower Resilience)

SingleStore enables retryWrites by default, which provides higher resilience against network errors. Disabling the retryWrites setting will improve latency for write operations, but the application might need to manually handle errors due to transient network conditions.

"mongodb://<user>:<password>@svc-XXXX.svc.singlestore.com:27017/?retryWrites=false&authMechanism=PLAIN&tls=true&loadBalanced=true"

SingleStore recommends leaving retryWrites enabled for ingesting data.

Verification instructions

Note: You must install cosign to verify the authenticity of the SingleStore file.

Use the following steps to verify the authenticity of singlestoredb-server, singlestoredb-toolbox, singlestoredb-studio, and singlestore-client SingleStore files that have been downloaded.

You may perform the following steps on any computer that can run cosign, such as the main deployment host of the cluster.

  1. (Optional) Run the following command to view the associated signature files.

    curl undefined

  2. Download the signature file from the SingleStore release server.

    • Option 1: Click the Download Signature button next to the SingleStore file.

    • Option 2: Copy and paste the following URL into the address bar of your browser and save the signature file.

    • Option 3: Run the following command to download the signature file.

      curl -O undefined

  3. After the signature file has been downloaded, run the following command to verify the authenticity of the SingleStore file.

    echo -n undefined |
        cosign verify-blob --certificate-oidc-issuer https://oidc.eks.us-east-1.amazonaws.com/id/CCDCDBA1379A5596AB5B2E46DCA385BC \
          --certificate-identity https://kubernetes.io/namespaces/freya-production/serviceaccounts/job-worker \
          --bundle undefined \
