Statistical data quality determination for storage systems

摘要

Techniques are described for enabling or suspending access to one or more datastores based on a determined quality of the stored data. The datastores may use relational or non-relational formats. User-specified rules may be applied to statistically determine the data quality of at least a portion of the data in the datastore. The rules may perform statistical tests on the data, such as determining whether an amount of stored data is within a margin of a historical average, whether a number of records storing particular data is within a historical average, and so forth. Based on the rules, a flag may be set to indicate the determined data quality. Access to the data may be based on the value of the flag.
