MongoDB storage provider for PROVANCE (ILedgerStore) with deterministic ordering and single-writer lease support.
Get Started
$ dotnet add package Provance.Storage.MongoDBReadme
Provance.Storage.MongoDB
MongoDB storage provider for PROVANCE (ILedgerStore), including a simple single-writer lease mechanism.
- NuGet:
Provance.Storage.MongoDB
Install
dotnet add package Provance.Storage.MongoDB
Configure
{
"MongoDb": {
"ConnectionString": "mongodb://localhost:27017",
"DatabaseName": "provance",
"CollectionName": "ledger_entries_v1"
}
}
Register
using Provance.Storage.MongoDB.Extensions;
builder.Services.AddProvanceMongoStorage(builder.Configuration);
What it creates
- Ledger entries collection (your configured
CollectionName) - Lock/lease collection:
provance_locks
Recommended indexes (v0.0.3+ new ledger collection):
- chain head lookup by
Sequence(descending) - lookup by
Id - unique
Sequence(prevents duplicates and enforces deterministic ordering)
The MongoDB store creates these indexes automatically on startup. If your Mongo user cannot create indexes, initialization will fail. In that case, create the indexes manually.
