Question 1

How do I install levigo with a custom LevelDB path?

Accepted Answer

Use CGO_CFLAGS and CGO_LDFLAGS to specify include and library paths, as shown in the README. For example, set CGO_CFLAGS="-I/path/to/include" and CGO_LDFLAGS="-L/path/to/lib" before running go get.

Question 2

levigo vs goleveldb: which is better for Go projects?

Accepted Answer

levigo wraps LevelDB's C API for performance close to the original, while goleveldb is a pure Go implementation. Choose levigo if you need exact LevelDB features, or goleveldb for easier deployment without C dependencies.

Question 3

Can I use snappy compression with levigo?

Accepted Answer

Yes, but you must explicitly add "-lsnappy" to CGO_LDFLAGS during build, as explained in the README. Ensure snappy's library path is included, and place -lsnappy after the path.

Question 4

How to write a custom comparator in levigo?

Accepted Answer

Custom comparators must be written in C in your own library, as levigo doesn't provide a pure Go interface. An example is available in the examples directory of the repository.

Question 5

Is levigo actively maintained and stable?

Accepted Answer

The project shows build and documentation badges, indicating some maintenance. However, it's a minimal wrapper with infrequent updates; check the GitHub repo for recent activity or issues.

Question 6

What are the minimum LevelDB versions supported by levigo?

Accepted Answer

levigo requires LevelDB 1.7 or higher, as stated in the README. For older versions, a separate fork exists, but updating to the latest LevelDB is recommended for compatibility and features.
