Disclosed are various embodiments for a token management application. A data block tokenization call to a data layer service fails when a data store is unavailable. The token management application issues a temporary data token to the service calling the data layer service. The token management application completes the data block tokenization call on behalf of the service to obtain a valid data token. The valid data token is then communicated to services having the temporary data token.

Data layer service availability

Techniques are described for migrating data from a first table to a second table while transforming at least one characteristic of the data. Characteristics transformed may include one or more of an encryption key or method, a table schema, a data structure, or a storage infrastructure. Migration may be performed in two or more phases. A first phase may migrate and transform a majority of the data, such as data that is older than a certain threshold age. A second phase may migrate and transform the remaining, newer data. A status table may indicate which tables are active and are to be written to and read from during data writing and data consuming processes. Moreover, embodiments support data replication across multiple regions.
