Question 1

How do I use changefeeds for real-time updates in RethinkDb.Driver?

Accepted Answer

The driver supports changefeeds via methods like `.RunChanges<T>()` and integrates with Reactive Extensions for streaming data. You can subscribe to table or document changes and handle them asynchronously in C#, similar to the examples in the wiki for real-time applications.

Question 2

RethinkDb.Driver vs MongoDB C# driver for a new project?

Accepted Answer

Choose RethinkDb.Driver if you need RethinkDB's specific features like real-time changefeeds or ReGrid file storage. For broader ecosystem support, community size, and ORM options, MongoDB's driver is more established. This driver excels in deep ReQL integration but locks you into a niche database.

Question 3

How to set up connection pooling with RethinkDb.Driver?

Accepted Answer

The driver offers strategies like round-robin and epsilon-greedy pooling, configurable via connection builders. Refer to the wiki's 'Connections & Pooling' section for code examples on initializing pools, tuning parameters, and handling failover in distributed setups.

Question 4

Can I use LINQ queries with RethinkDb.Driver?

Accepted Answer

Yes, it includes a LINQ to ReQL provider that translates C# LINQ expressions into ReQL queries. However, as noted in the documentation, some advanced LINQ features might not be fully supported, so you may need to fall back to raw ReQL for complex operations.

Question 5

What does the commercial license for SSL cost?

Accepted Answer

Pricing is not detailed in the README; you must contact Bit Armory Inc. for quotes. This adds uncertainty for budgeting, especially for startups or open-source projects that require encrypted connections without upfront cost transparency.

Question 6

How to store and retrieve files using ReGrid in C#?

Accepted Answer

ReGrid is built into the driver—use the `Bucket` class to upload, download, and manage files with methods like `UploadAsync` and `OpenDownloadStream`. The wiki provides examples for handling revisions, seekable streams, and distributed storage across RethinkDB shards.
