How to specify the namespace value for a generated schema for different databases like MongoDB, Couchbase and AVRO?

Title:

How to specify the namespace so that it appears in the generated schema? How to set this value for MongoDB, Couchbase and AVRO?

Description:

The concept of name spacing varies for each of the different NoSQL databases.

Resolution:

Please find the details for specifying name spacing for different database like:

For MongoDB:

In MongoDB, a namespace relies on the collection and the naming pattern it uses is <database>.<collection>. Collections can be further organized by using a namespace/package notation style with a “dot” separator such as “logs.dev”.

For Couchbase:

Couchbase does not have namespaces. A variety of documents can be stored under a bucket. There is a limitation of how many buckets can be created for a cluster. Therefore, buckets are not a suitable means of namespacing. However, Couchbase suggests to replace namespacing by using semantic prefixes and suffixes in your key names and to use document types by creating a field that denotes the type of document such as “type”. 

For AVRO:

AVRO schema states that named types (records, enums, fixed) can be namespaced to fully qualify a name. This value can be defined via the properties panel when creating records or assigning named types to record fields.
