Ebipụtala ntọhapụ nke libmdbx 0.13.2 (MDBX), na-emejuputa nchekwa data bara uru bara uru dị elu. A na-ekesa koodu libmdbx n'okpuru ikike Apache 2.0. A na-akwado sistemu arụ ọrụ na ihe owuwu niile, yana Russian Elbrus 2000. libmdbx na-enye API mepere emepe maka C ++, yana mgbakwunye na-akwado ịnụ ọkụ n'obi na asụsụ Rust, Haskell, Python, NodeJS, Ruby, Go, Nim. , Deno, Scala.
N'akụkọ ihe mere eme, libmdbx bụ nrụgharị miri emi nke LMDB DBMS ma dị elu karịa nna nna ya na ntụkwasị obi, nhazi atụmatụ na arụmọrụ.
