PersistedConcurrentSortedList

PersistedConcurrentSortedList is an F# library for ordered key/value storage with on-disk persistence.

It is designed for workloads where:

  • the dataset is loaded once or rebuilt at startup,
  • reads dominate after initialization,
  • only occasional small updates are expected,
  • ordered queries such as FirstLastN* still matter.

Features

  • ordered in-memory index over persisted values
  • Add, Update, Upsert, and Remove
  • TryGetValue, key hashing helpers, and buffered/non-buffered value loading
  • protobuf and FsPickler serialization paths
  • support for F# records and discriminated unions in the value path

Package

NuGet package id:

PersistedConcurrentSortedList

Quick Start

See QuickStart.fsx for a runnable sample.

let pcsl =
    PersistedConcurrentSortedList<string, fstring>(
        20,
        @"c:\pcsl",
        "test",
        PCSLFunHelper<string, fstring>.oFun,
        PCSLFunHelper<string, fstring>.eFun
    )

pcsl.Add("OGC", A [| S "GG" |], 3000) |> ignore
pcsl.Upsert("123456", S "ORZ")

let found, cell = pcsl.TryGetValue("OGC")

Serialization

The library currently supports:

  • FAkka.ProtoBuf.FSharp
  • FAkka.FsPickler
  • FAkka.FsPickler.Json

The protobuf path includes the compatibility handling required by the current fCell2<'T> model used in this repository.
