A service implements techniques for modifying a data table stored in a key-value or non-relational database via a table-oriented schema. In some aspects, a request to modify a table-oriented schema of a table of data may be received. In response to the request, an association between a customer identifier of elements of the table and an internal identifier of elements of the table may be stored that updates a prior association between a customer identifier and an internal identifier. The table-oriented schema of the table may be modified using one or more keys that are generated using the internal identifier.

A data storage service implements encoding techniques for generating compound partition keys, compound clustering keys, or a combination for more flexibility in storing data in a key-value database system. In some aspects a request to store data with multiple partition keys and/or multiple clustering keys may be received. Length information may be added to the partition keys, and the results concatenated together to form a compound partition key used to store the data in the database. Ordering information may be added to the clustering keys, and the results concatenated together to form a compound clustering key, to be used in storing and sorting data in the database. In some cases, the clustering keys may be made a uniform length, such as by padding keys, as necessary, to have a length that is a multiple of an arbitrary number, and then dividing the clustering keys into chunks of that arbitrary number.
