Abstract: Example systems and methods for cloning catalog objects are described. In one implementation, a method includes creating a copy of a catalog object without copying a data associated with the catalog object by only coping metadata associated with the object. The method further includes modifying, by one or more processors, the data associated with the catalog object independently of the copy of the catalog object.

Abstract: Example systems and methods for cloning catalog objects are described. In one implementation, a method identifies an original catalog object associated with data and creates a duplicate copy of the original catalog object without copying the data itself. The method allows access to the data using the duplicate catalog object and supports modifying the data associated with the original catalog object independently of the duplicate catalog object. The duplicate catalog object can be deleted upon completion of modifying the data associated with the original catalog object.

The method further includes modifying, by one or more processors, the data associated with the catalog object independently of the copy of the catalog object such that modified data is not visible to the copy of the catalog object and wherein the modified data is not visible to the catalog object in a database. The method further includes deleting the copy of the catalog object following completion of the modification of the data associated with the catalog object.

Abstract: The subject technology generates a first data structure including first metadata and a second data structure including second metadata, the first metadata corresponding to a set of micro-partitions, the second metadata for a grouping of the first metadata, the second data structure including information associating the second metadata to the first metadata. The subject technology stores the first data structure and the second data structure in storage as a first file and a second file. The subject technology stores third metadata for a table, the third metadata comprising: cumulative table metadata comprising global information about a plurality of micro-partitions of the table, the cumulative table metadata being stored in a metadata micro-partition associated with the table.

Abstract: A system and method for pruning data based on metadata. The method may include receiving a query that includes a plurality of predicates and identifying one or more applicable files including database data satisfying at least one of the plurality of predicates. The identifying the one or more applicable files including reading metadata stored in a metadata store that is separate from the database data. The method further includes pruning inapplicable files including database data that does not satisfy at least one of the plurality of predicates to create a reduced set of files and reading the reduced set of files to execute the query.

Abstract: A system, apparatus, and method for processing queries wherein the query includes a request to access or delete data and accessing metadata associated with the set of data, the metadata defining data characteristics of the set of data and identifying at least sets of data that need or not need to be accessed or deleted based on the metadata without accessing the actual data in the set of data; also methods to optimize processing of some operations based on the collected metadata on data.

Abstract: Example systems and methods for cloning catalog objects are described. In one implementation, a method includes copying first metadata of a first catalog object to create second metadata of a second catalog object such that a second portion of the second metadata and a first portion of the first metadata are associated with same data of a same data file, and generating a response to a data storage or data retrieval request directed to the first catalog object by accessing the data file using the second metadata of the second catalog object.
