FAQ

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

On this page

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. In our benchmark, 1,000,000 idle databases cost about $9 a month in storage (local object storage, 200 documents per database, S3 Standard storage prices).

Will my application work?#

Check Compatibility. 1,081 of 1,081 differential tests pass against a reference MongoDB 7.0, and about 97% of the MongoDB calls in 10 open-source apps are supported. 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.
