    摘要: Mechanisms for performing database queries are provided. With these mechanisms, in response to a query request, a query plan intended for minimum query response time and a query plan intended for minimum query total time for the query request are obtained execution of the minimum query response time query plan and the minimum query total time query plan is started. Before the execution of the minimum query total time query plan reaches a specified point, an initial query result obtained from the execution of the minimum query response time query plan is output. In response to the execution of the minimum query total time query plan reaching the specified point, continuing the execution of the minimum query total time query plan to output remaining query results.

    摘要: An index is created for a database by selecting at least one column of a database table as a basis to create the index, generating at least one index of a tree structure according to the at least one column, where a pointer stored in a leaf node of the at least one index is null. In an example embodiment, a value to a pointer is stored in a leaf node according to an intermediate result in response to the intermediate result being generated, where the pointer stored in the leaf node points to a data page storing the intermediate result. The created index can be reused and the intermediate result can be effectively used, such that the efficiency of database operation is improved.

    摘要: Methods are provided to obtain recombinant microbial cells having at least one genetic modification that increase the buoyant density of a recombinant microbial cell or the buoyant density of inclusion bodies produced within a recombinant microbial cell. Exemplified are genetic modifications that increase the buoyant density of a recombinant microbial cell expressing heterologous peptides and polypeptides. Increasing expression of the genes ysaB, glyQ, glyS or a combination thereof within the recombinant microbial cell produces cells or inclusion bodies having higher buoyant density. A similar effect was achieved by decreasing or disrupting expression of the endogenous gltA gene. Increases in buoyant density render peptide production more efficient with respect to time and costs.
