Intelligent, transaction-aware table placement minimizes cross-host transactions while supporting full transactional semantics and delivering high throughput at low resource utilization. This placement reducing delays caused by cross-host transaction coordination. Examples determine a count of historical interactions between tables, based on at least a transaction history for a plurality of cross-table transactions. Each table provides an abstraction for data, such as by identifying data objects stored in a data lake. For tables on different hosts, having high count of historical interactions, potential cost savings achievable by moving operational control of a first table to the same host as the second table is compared with the potential cost savings achievable by moving operational control of the second table to the same host as the first table. Based on comparing the relative cost savings, one of the tables may be selected. Operational control of the selected table is moved without moving any of the data objects.

Deleting directories in a virtual distributed file system (VDFS), and non-virtual file systems, involves changing the name of a selected directory to a unique object identifier (UID) and moving the selected directory, named according to the UID, to a deletion target directory. A recursive process, implemented using a background deletion thread, starts in the current directory and identifies objects in the current directory. For an object that is a file or an empty directory, the object is added to a deletion queue. For an object that is a directory that is not empty, the recursion drops down into that directory as the new current directory. When the recursion has exhausted the selected directory, or some maximum object count has been reached, the objects identified in the deletion queue are deleted. This approach can also be used for file operations other than deletion, such as compression, encryption, and hashing.

Today, stateful services (e.g., firewall services, load balancing services, encryption services, etc.) running inside guest machines (e.g., guest virtual machines (VMs)) can be very expensive, particularly for applications that need to handle large volumes of firewall, load balancing, and VPN (virtual private network) traffic. In some such cases, these stateful services can cause bottlenecks for datacenter traffic going in and out of the datacenter, and result in significant negative impacts on customer experiences. Additionally, service-critical guest machines may need to migrate from one host to another, and need to maintain service capability and throughput before and after the migration such that from a user perspective, the service is not only uninterrupted, but also performant.

To implement secure block cloning on file systems that support block cloning, a computer security application is executed on a computer system deploying a file system that supports block cloning. The computer security application receives a block cloning command to clone a source file to a target file. Before the computer system executes the block cloning command, the computer security application identifies a trust status associated with the source file. The trust status is identified by looking up a base inventory that stores trust data associated with multiple files stored on the file system. The multiple files include the source file. Based on the trust status associated with the source file, the computer security application determines that the trust status associated with the source file is trustworthy. In response to determining that the source file is trustworthy, the computer security application applies the trust status associated with the source file to the target file.
