Abstract: A method, a master database node and a subscriber database node for optimizing index. The method for optimizing index includes: checking, by a master database node, if role information of an index matches role information of the master database node, when the index is added into the master database node; updating database information by using the index when the role information of the index matches the role information of the master database node. In this invention, unnecessary indexes in the master database node and the subscriber database node are reduced while keeping the schema the same. Furthermore, unnecessary logs transmitted from the master database node to the subscriber database node are reduced.

Abstract: The systems described herein are configured to enhance the efficiency of memory in a host file system with respect to hosted virtual file systems. In situations when the hosted virtual file systems use smaller file block sizes than the file block sizes of the host file system. During storage of a file, a file block is assigned a block address and unmapping bits. The block address and unmapping bits are stored in a pointer block or other similar data structure associated with the file. Particularly, the block address is stored in a first address block and the unmapping bits are stored in at least one additional address block located in proximity to the block address, such that the unmap granularity of the file is not limited by the fixed size of address blocks in the system.

Abstract: A computer-implemented method includes performing retiming using a circuit design to determine a retimed variation to the circuit design. The circuit design includes a first set of registers with defined power-up states and the variations each comprise a second set of registers that correspond to the first set of registers. The method includes maintaining fixed power-up states for the second set of registers in the variations. The fixed power-up states for the second set of registers are equivalent to the defined power-up states of the first set of registers. The method includes identifying registers of the second set of registers involved in an initial state conflict, and performing a mitigating action to resolve the initial state conflict to enable retiming to continue while maintaining functionally equivalent behavior as the circuit design. Various choices of initial states are also explored during retiming to increase the effect of retiming.
