mongodb-memory-server-percona

Drop-in replacement for mongodb-memory-server that downloads and runs Percona Server for MongoDB with the open-source inMemory storage engine. Version 0.1.1 supports linux/x64 only (per Percona binary tarballs), requires Node >=20, and peer depends on mongodb ^6.0.0 and mongodb-memory-server-core >=10 <12. It automatically fetches Percona binaries (~440 MB on disk) on first use, caches them, and fixes ABI-incompatible libldap/libssl by staging a wrapper with correct LD_LIBRARY_PATH. Key differentiator: unlike mongodb-memory-server (which only ships WiredTiger with Community builds), this gives you an open-source inMemory engine (10-40% faster writes, no journal) that MongoDB Enterprise normally restricts. Matches the full mongodb-memory-server API and ships TypeScript types.
