20120030169 | APPLICATION INSTANCE AND QUERY STORES - An instance persistence command for an update to a state of an instance of an application can be issued. In response to the persistence command, a transaction with an instance store can be initiated. As part of the transaction, a first representation of the update can be stored in the instance store and a second representation of the update can be stored in a queue. The transaction can be committed after storing the first and second representations. After the transaction is committed, the second representation can be processed to store a third representation of the update in a query store. Application instance state information in the query store can be updated and queried without locking the instance store so that such operations in the query store can be performed asynchronously with operations in the instance store. | 02-02-2012 |
20120158655 | NON-RELATIONAL FUNCTION-BASED DATA PUBLICATION FOR RELATIONAL DATA - A data publication system is described herein that provides a data replication model that combines benefits of data distribution from non-relational paradigms with the benefits of deeply integrating datasets via relational database paradigms. The system allows the creation of programmatic functions for extracting subsets of data stored in any source model, extracting data from a variety of sources, and republishing that data in a target model built upon the aggregated source data. The target model can provide standard relational paradigms across a set of data from multiple sources, whether or not the original sources were relational in nature. The system applies known paradigms for data replication based upon programmatic functions as a means for data replication and integrates this method for data duplication and replication based upon arbitrary functions with the power of relational database systems to process associated entities of data in highly efficient ways. | 06-21-2012 |

The distributed system includes a plurality of computer systems, each having a read-write computer and a data storage unit. Data is replicated from a particular data storage unit to other data storage units using publish-subscribe model. A read-write computer receives the replicated data, processes the data for any conflicts and stores it in the data storage unit. If a data storage unit fails, another data storage unit that has latest data corresponding to the failed data storage unit is determined and the latest data is replicated to other data storage units. Accordingly, the distributed system continues to have the data of the failed data storage unit. The failed data storage unit may be reconstructed using data from one of the other data storage units in the distributed system. | 07-10-2014 |
20140244584 | SYSTEM AND METHOD FOR IMPLEMENTING CACHE CONSISTENT REGIONAL CLUSTERS - When multiple regional data clusters are used to store data in a system, maintaining cache consistency across different regions is important for providing a desirable user experience. In one embodiment, there is a master data cluster where all data writes are performed, and the writes are replicated to each of the slave data clusters in the other regions. Appended to the replication statements are invalidations for cache values for the keys whose values have been changed in the master data cluster. An apparatus in the master data cluster logs replication statements sent to the slave databases. When a slave database fails, the apparatus extracts the invalidations intended for the failed database and publishes the invalidations to a subscriber in the region of the failed database. The subscriber sends the invalidations to the local caches to cause stale data for those keys to be deleted from the caches. | 08-28-2014 |

20140330781 | Parallel Filesystem Traversal For Transparent Mirroring of Directories and Files - A system and method for parallel file system traversal using multiple job executors is disclosed. The system includes a pool of job executors, a job queue, and a trigger tracker. An object, representative of a node in the filesystem, is added (i.e., pushed) to the job queue for processing by an job executor. The job queue assigns (i.e., pops) objects to job executors in accordance to a LIFO (Last In First Out) ordering. Then the job executor performs an action such as copy. In one embodiment, the trigger tracker follows the processing of a child nodes to a particular child node. Thus, the filesystem is being traversed by several job executors at the same time. | 11-06-2014 |

Source volume metadata having records including information on data sets in the source volume is copied to target volume metadata. A metadata index is generated indicating locations of the records in the target volume metadata having information on the data sets in the target volume. The metadata index is used to access the records in the target volume metadata when accessing data sets in the target volume. | 03-12-2015 |

20150310127 | N-Way Inode Translation - Example apparatus and methods concern storing additional information about inodes to facilitate n-way inode translation between local inode spaces and external inode spaces. Example apparatus and methods also concern publishing information about actions that affect inodes to facilitate n-way inode translation. Additional data is added to local file systems so that a local file system can determine whether an inode for which an action is requested or reported is a native inode or an imported inode. The additional data added to the local file systems through the updated inode data storage and inode action publication also facilitates determining which local inode to act on based on the n-way inode translation mechanism. | 10-29-2015 |
20150339314 | COMPACTION MECHANISM FOR FILE SYSTEM - Increasing data storage efficiency includes receiving an amendment to a set of data objects. The amendment includes new or changed content relative to an earlier version of the set of data objects. The amendment includes one or more data lookup tables. The set of data objects includes data blocks associated with the data lookup tables. The set of data objects is examined to identify data ranges (e.g., byte ranges) that are not referenced in the set of data lookup tables of the amendment. In data ranges that are identified as not referenced in the data lookup tables, the data is replaced with data that is more compressible (for example, the range may be filled with zero values). The set of data objects may be compacted by compressing data including the identified unreferenced data ranges. | 11-26-2015 |
