A system of redistributing partitions across servers having multiple partitions that each process transactions. Where the transactions are related to one another and the transactions are able to access one or a set of partitions simultaneously. The system comprising: a monitoring module operable to determine a transaction rate of the number of transactions processed by the multiple partitions on the first server; an affinity module operable to determine affinity between partitions, wherein the affinity being a measure of how often group transactions access sets of respective partitions; a partition placement module operable to determine a partition mapping in response to a change in a transaction workload on at least one partition on the first server, the partition placement module operable to receive input from at least one of: a server capacity estimator module; wherein server capacity estimator module is operable to determine the maximum transaction rate and use a pre-determined server-capacity-function; the affinity module; and distributing the partitions according to the determined partition mapping from the first server to a second server.

A computer implemented method comprising: storing a set of social media objects, each social media object comprising at least one word. The method comprises identifying a subset of relevant social media objects from the set of social media objects by: storing at least one content article, extracting at least one keyword from at least one content article, ranking each extracted keyword with an importance value, searching each of the social media objects for each extracted keyword with an importance value that is higher than a predetermined value, and adding each social media object which comprises an extracted keyword with an importance value that is higher than the predetermined value to a subset of relevant social media objects. The method further comprises outputting the subset of relevant social media objects to a user.
