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.

Concurrent Multi-Insert Examples

To perform a trickle load into SingleStore, you can run concurrent processes that each load data in batches using the INSERT command to insert up to several thousand rows in each statement. When loading a large volume of data, loading a row at a time is a resource-intensive and time-consuming process due to per-statement overhead, so batching is preferred.

For bulk loading into SingleStore, you can use the LOAD DATA command or pipelines. LOAD DATA is preferable for a small number of files that are not extremely large, loaded in an initial step before working with the data. For very large data sets where parallel loading is important, pipelines are preferred. Moreover, pipelines can perform continuous loads as new files or messages arrive.

The following examples demonstrate how to perform concurrent multi-inserts with different tools/languages.

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 \
          --new-bundle-format -
    Verified OK
