Ntọhapụ kwụsiri ike nke mbụ nke FerretDB, mmejuputa MongoDB dabere na PostgreSQL DBMS

Ebipụtala ntọhapụ nke ọrụ FerretDB 1.0, nke na-enye gị ohere iji PostgreSQL dochie DBMS MongoDB nke dabere na akwụkwọ na-enweghị mgbanwe na koodu ngwa. A na-emejuputa FerretDB dị ka ihe nkesa proxy nke na-atụgharị oku na MongoDB n'ime ajụjụ SQL na PostgreSQL, na-ekwe ka PostgreSQL mee ihe dị ka ezigbo nchekwa.
