FAQ
Short answers about sleeping databases, durability, protocols and cost.

Is this MongoDB?#
No. FENVIX is its own database engine on object storage. It speaks the MongoDB protocol, so MongoDB drivers and tools connect to it.
How fast does a sleeping database answer?#
It wakes on the first request and reads its files from the bucket, so the first request after a sleep is slower than the ones after it. A database that is kept awake never sleeps and answers every request at the same speed.
Can I lose data if a server crashes?#
A write is acknowledged only once it is in the bucket. In our tests, 20 forced kills lost no acknowledged write.
What does an idle database cost?#
Storage only. A closed database makes no requests. Estimated at about $9 a month in storage for 1,000,000 idle databases, calculated from measurements on local disk (200 documents per database) at S3 Standard prices. It has not been run with 1,000,000 databases on S3.
Will my application work?#
Check Compatibility. 1,081 of 1,081 differential tests pass against a reference MongoDB 7.0, and 1,237 of 1,268 MongoDB 7.0 features, compared against a real MongoDB server, give the same result. Your own code may use something that is not.
Can I try it?#
Yes. Sign in to the console, create a database and copy its connection string.
