go-driver | The official ArangoDB | Database library

bson.D models a document, with an ordered list of key-value pairs, where the key is the property name, value is the property's value.

So if you intend to use bson.D to model documents, you always have to write a bson.D composite literal where there's a document in the equivalent shell command.

So your update document must look like this:

I presume you are trying to combine those two queries with OR operator. Another thing, I saw two similar clauses between the two, it's "unlocked": false and "deletedAt": nil.

You can have shorter query like below:

Your query covers all collections, however usually it should be per collection, i.e. per namespace. In earlier MongoDB release the documents where like this:

The example in the readme says the following:

mongo.Connect() creates a new mongo.Client and initializes it, but does not (necessarily) create connections to the DB server.

To actually create a connection and check if the server is reachable (without executing a query), you may use the Client.Ping() method. This will return an error if the server is not reachable.

The official mongodb driver manages an internal pool of connections. Connections are not closed immediately after use, instead they are put back into the pool so when a connection is needed to carry out an operation, an idle connection can be used from the pool immediately. This is the intended behavior. You may configure its size via the options.ClientOptions you pass to mongo.Connect().

See ClientOptions.SetMaxPoolSize():

SetMaxPoolSize specifies that maximum number of connections allowed in the driver's connection pool to each server. Requests to a server will block if this maximum is reached. This can also be set through the "maxPoolSize" URI option (e.g. "maxPoolSize=100"). The default is 100. If this is 0, it will be set to math.MaxInt64.

Example setting up a client with limited connections, and pinging it:

Please, change the following line in the .env file:

It should be

Make sure your VSCode terminal is a bash one, not a CMD or Powershell.

In a CMD or Powershell, the syntax var=xxx cmd would not be correctly interpreted as: set a variable and execute a command inheriting its environment variables, including the one set.

uint8 is an alias to byte, and []byte is a special type, it's handled differently than other slice types (not as a slice of numbers). []byte values are encoded using bsoncodec.ByteSliceCodec and other slice values are encoded using bsoncodec.SliceCodec.

Use a slice of any other number type, e.g. []int8 or []int:
