Query Azure Table Storage using F#

Sun, 29 Dec 2024 00:00:00 +0000

When looking at the signature of the TableClient.QueryAsync method in Azure.Data.Tables SDK, it is not clear how to use it. It returns a AsyncPageable<T>. Fortunately that again implements the IAsyncEnumerable<T>, which means that we can use the Fsharp.Control.TaskSeq library to get the resulting entities.

Install FSharp.Control.TaskSeq NuGet-package to your project.
open FSharp.Control
Write your code using the TaskSeq module

let getPartitionRows (tableClient: TableClient) (partition: string) =
    task {
        return!
            tableClient.QueryAsync<TableEntity>(filter = $"PartitionKey eq '{partition}'")
            |> TaskSeq.map fromEntity
            |> TaskSeq.toArrayAsync
    }

This is written as a reminder to myself, so that I can easily find it again
