Question 1

Is Pogreb good for caching in Go?

Accepted Answer

Yes, Pogreb excels in caching scenarios due to its fast random lookups and low memory usage, making it ideal for read-heavy applications like session stores or configuration caches. However, it lacks features like TTL (time-to-live) out of the box, so you may need to implement expiration logic manually.

Question 2

How to handle large datasets with Pogreb?

Accepted Answer

Pogreb supports larger-than-memory datasets through efficient disk persistence and low RAM usage. Use it by opening a database with pogreb.Open and ensure your system has sufficient SSD storage for optimal performance, as benchmarks were run on SSDs.

Question 3

What are the main limitations of Pogreb?

Accepted Answer

Pogreb lacks range scans and has slow recovery for large databases due to hash table indexing. It's optimized for point lookups, so avoid it for applications needing sorted data queries or frequent large-scale writes where quick recovery is essential.

Question 4

Pogreb vs BadgerDB for Go projects?

Accepted Answer

Pogreb is faster for random reads but lacks range scans and has slower recovery, while BadgerDB offers richer features like range queries and better write performance. Choose Pogreb for pure read-heavy workloads and BadgerDB for more general-purpose use with ordered data needs.

Question 5

How to iterate over all items in Pogreb?

Accepted Answer

Use the ItemIterator from DB.Items() to loop through key-value pairs, as shown in the README example. Be cautious with large databases, as iteration might be slower without indexed ordering, and handle errors like pogreb.ErrIterationDone.

Question 6

Can Pogreb handle concurrent writes safely?

Accepted Answer

Yes, all DB methods are concurrent-safe for multiple goroutines, so you can perform Put, Get, and Delete operations simultaneously without data races. However, for high-write scenarios, performance might degrade compared to read operations.
