/create/type

URL: http://<db.host>:<db.port>/create/type

Creates a new type describing the layout of a table. The type definition is a JSON string describing the fields (i.e. columns) of the type. Each field consists of a name and a data type. Supported data types are: double, float, int, long, string, and bytes. In addition, one or more properties can be specified for each column which customize the memory usage and query availability of that column. Note that some properties are mutually exclusive--i.e. they cannot be specified for any given column simultaneously. One example of mutually exclusive properties are data and store_only.

A single primary key and/or single shard key can be set across one or more columns. If a primary key is specified, then a uniqueness constraint is enforced, in that only a single object can exist with a given primary key column value (or set of values for the key columns, if using a composite primary key). When inserting data into a table with a primary key, depending on the parameters in the request, incoming objects with primary key values that match existing objects will either overwrite (i.e. update) the existing object or will be skipped and not added into the set.

Example of a type definition with some of the parameters:

{"type":"record",
"name":"point",
"fields":[{"name":"msg_id","type":"string"},
                {"name":"x","type":"double"},
                {"name":"y","type":"double"},
                {"name":"TIMESTAMP","type":"double"},
                {"name":"source","type":"string"},
                {"name":"group_id","type":"string"},
                {"name":"OBJECT_ID","type":"string"}]
}

Properties:

{"group_id":["store_only"],
"msg_id":["store_only","text_search"]
}
