how did you compile the binary? looks like you have debug checks enabled. Read this to understand more: https://github.com/facebook/rocksdb/blob/master/Makefile#L24-L35

[superwood]

i compile it for some debug-info. Does it slow the db recovering?

[igorcanadi]

Yes. It slow entire DB operation.

[igorcanadi]

even if you compile with DEBUG_LEVEL=0, we still have some debugging information.

[igorcanadi]

Did this solve your problem?
