摘要： A method, system and computer program product for dynamic map template discovery and map creation may include determining a frequency of use of a data object in a database and discovering a dynamic map template corresponding to the data object based on the frequency of use of the data object. The method may also include creating a dynamic map from the dynamic map template in response to discovering the dynamic map template.

摘要： A method, system and computer program product for placing data in shards on a storage device may include determining placement of a data set in one of a plurality of shards on the storage device. Each one of the shards may include a different at least one performance feature. Each different at least one performance feature may correspond to a different at least one predetermined characteristic associated with a particular set of data. The data set is cached in the one of the plurality of shards on the storage device that includes the at least one performance feature corresponding to the at least one predetermined characteristic associated with the data set being cached.

摘要： A TTL value for a data object stored in-memory in a data grid is dynamically adjusted. A stale data tolerance policy is set. Low toleration for staleness would mean that eviction is certain, no matter the cost, and high toleration would mean that the TTL value would be set based on total cost. Metrics to report a cost to re-create and re-store the data object are calculated, and the TTL value is adjusted based on calculated metrics. Further factors, such as, cleanup time to evict data from a storage site, may be considered in the total cost.

摘要： A method for improving replication persistence in a caching appliance structure can begin when a primary catalog service receives a command to instantiate a data partition. The primary catalog service can manage a collective of caching appliances in a networked computing environment. The data partition can include a primary shard and at least one replica shard. The primary shard of the data partition can be stored within a memory space of a first caching appliance. The at least one replica shard of the data partition can be stored within a non-volatile storage space of a second caching appliance. The first and the second caching appliances can be separate physical devices. The memory space of the second caching appliance that could have been used to store the at least one replica shard can be available for storing primary shards for other data partitions, increasing the capacity of the collective.
