Abstract: A method may include obtaining a table including a table schema including definitions of native fields, adding a value of a custom field to the table by inserting, in a native field, a native field value including (i) an identifier (ID) of the custom field and (ii) the value of the custom field, and storing a definition of the custom field in a custom field registry external to the table. The custom field may be undefined by the table schema. The method may further include receiving a request to perform an operation on the table, generating, from the request, a query on a subset of the native fields and the custom field, executing the query to obtain query results, and transmitting, in response to the request, the query results.

Abstract: A computer-implemented system and method for achieving strong consistency in an eventually consistent distributed system. The system comprises a database and an application server hosting a computer software product that a user subscribes to in order to access the product via a user device over a network. The application server receives a first service request from the user device for obtaining a first set of features associated with the user. The application server may ensure that the user receives a useable and correct set of features.
