Validation of a migration task to migrate data from one data store to another may be performed prior to the migration of the data. Parameters associated with the migration may be evaluated according to one or more types of validations for the migration task. In some embodiments, users may specify the validations to perform for the migration task. A determination as to whether the migration task is valid may be performed for the migration task based on the parameter evaluations. A result indicating whether the migration task is valid may be provided to a user.

Migration task validation before data migration

Described herein are system and methods for mitigating index contention issues in databases. The database server may generate additional storage locations to prevent overloading one or more current storage locations. A variety of database conditions may be used to trigger an increase or decrease in storage locations. In one embodiment, more storage locations may be generated when the amount of data records waiting to be written at a storage location exceeds or equals a threshold amount. Likewise, the database server may reduce the amount of current storage locations when the amount of data records is less than a threshold amount. The record identifiers may incorporate a location reference for their designated storage location. The reference may be a string that includes numbers, letters, or a combination thereof.

Systems and methods for reducing database index contention and generating unique database identifiers

Described herein are systems and methods for generating integrated identifiers that may be combined with database sequence values to create a high probability of uniqueness that minimizes assigning duplicate identifiers to one or more databases. The integrated identifier may be based in part on several identifiers associated with a database. This may include a numeric identifier assigned to the database, a name assigned to the database, or any other database property that may be relatively unique. In one embodiment, the integrated identifier may be associated with a sequence value for a database. While the sequence value may be unique within the database, the integrated identifier may be unique to other database identifiers. When an existing database is cloned, a new integrated identifier may be generated from the cloned database. New records stored in the new database may use the new integrated identifier, while the cloned records will remain unedited.
