Paravirtualization**: The hypervisor provides efficient hypercalls, and the guest OS uses drivers and kernel modifications to call these hypercalls. Enter paravirtualization, originally introduced in Xen, where the guest has been modified to be aware of the hypervisor and to make efficient hypercalls. The AMI and boot are now HVM.

Back in 2014, I wrote an article called Performance Tuning the Whole Query Plan. This is very efficient, as confirmed by the elapsed time of 13ms (all of which is CPU time). The structure of a b-tree index makes finding the next highest value very efficient — there is no need to scan through the duplicates. Test Environment.

Using SQL Server Management Studio (SSMS) and storing the events in a table requires reading the events, streaming to table storage followed by an order by event sequence query. Large traces can encounter the 32-bit SSMS memory limitations. public void Dispose() { Dispose(true); GC.SuppressFinalize(this); }.

However, ClickHouse is super efficient for timeseries and provides “sharding” out of the box (scalability beyond one node). Although such databases can be very efficient with counts and averages, some queries will be slow or simply non existent. Inserts are efficient for bulk inserts only. created_utc?? ?

Bloom filters present a space- and time-efficient alternative when a simple bitmap is infeasible due to space requirements. Complex bitmaps have supported multiple join columns and all batch mode data types since SQL Server 2014. This decompression can be performed efficiently using SIMD instructions, but it is still extra work.

tl;dr: I don’t want C++ to limit what I can express efficiently. Efficiency. The rules that are not efficient enough to implement in the compiler will always be relegated to optional standalone tools. That’s pretty easy to statically guarantee, except for some cases of the unused parts of lazily constructed array/vector storage.

SQL Server 2014 added the ability to perform parallel batch-mode grouped aggregation within a single Hash Match Aggregate operator. Columnstore storage. To understand this, it is necessary to first review how columnstore storage works at a high level: A compressed row group contains a column segment for each column.

They often get blindsided by vendor’s pitch and end-up making decision based on some fancy demos (see my post from 2014 on Adobe AEM ).
