            Computed property based on presence of non-required properties
            Asked 2022-Jan-27 at 02:01

            We know we can create a computed property based on other properties like so as per the docs,



            Answered 2022-Jan-27 at 02:01

            You can check optional properties for emptiness using the exists operator:

            Define a unique index in EdgeDB
            Asked 2020-Jul-29 at 19:10

            How do you define a unique index in EdgeDB?

            For simple properties you can add constraint exclusive which implicitly creates a unique index.



            Answered 2020-Jul-29 at 19:10

            You can add constraint exclusive on (...) to the containing type, where ... is an arbitrary scalar expression. To ensure the uniqueness of multiple properties, it should be a tuple (x, y):

            Define a composite index in EdgeDB
            Asked 2020-Jul-29 at 19:01

            How do you define a composite index in EdgeDB?

            The documentation states:

            The simplest form of index is an index, which references one or more properties directly:

            Is 35k rows/s slow or fast for EdgeDB?
            Asked 2020-Feb-05 at 19:40

            I'm testing EdgeDB locally, my host is a decent macbook pro and the database runs in docker:



            Answered 2020-Feb-05 at 19:40

            I reproduced the benchmark with a few changes: 1) I only measured the actual query runtime (connection time excluded); 2) EdgeDB server was running directly on a Linux host, not in Docker.

            My result:

            35038 records in 0.286s: 122314 records/s

            To compare, I loaded the same dataset directly into Postgres and ran a similar query with psycopg2. The result was nearly identical:

            35038 records in 0.285s: 122986 records/s

            This is not surprising, since once the query is compiled to SQL, the I/O overhead of EdgeDB over raw Postgres is negligible. Additionally, to stress-test the server better you need multiple concurrent clients, as we've done in our benchmarks.
