Q
How do shapes work in ArangoDB?
A
*Documents that have the similar structure (i.e., that have the same attribute names and attribute types) can share their structural information. The structure (called “shape”) is saved just once, and multiple documents can re-use it by storing just a pointer to their “shape”.
Q
Does ArangoDB support transaction?
A
ArangoDB provides support for user-definable transactions. Transactions in ArangoDB are atomic, consistent, isolated, and durable (ACID).
ArangoDB transactions are different from transactions in SQL. In SQL, transactions are started with explicit BEGIN or START TRANSACTION commands.

Q
Will I be able to choose how different collections are stored, or will it be a per-database choice?
A
It is a per server/cluster choice. It is not possible yet to mix modes or to use different storage engines in the same arangodb instance or cluster.
Q
Does ArangoDB support SQL?
A
*ArangoDB does not support SQL. SQL is not well-suited to cover the different data models in ArangoDB.
*ArangoDB brings its own declarative language called AQL (ArangoDB Query Language). If you are familiar with SQL you will probably feel quickly at home with ArangoDB. For syntax examples see the SQL to AQL comparison.

Q
Will I be able to go beyond the limit of RAM?
A
RocksDB Integration in ArangoDB:
