DuckDB combines SQLite properties such as compactness, the ability to plug in as a built-in library, single-file database storage, and a convenient CLI interface, with tools and optimizations for performing analytical queries covering a significant part of the Stored data, for example, that performs aggregation of all table contents or merges multiple large tables.

In this new version that is presented, it is worth noting that work continued on improving the storage format, in addition to the fact that a disk write mode has been implemented, in which when a large set of data is loaded in a transaction, the Data is compressed and streamed to a file from the database without waiting for the COMMIT command to commit the transaction.

The new version added support for parallel loading of data into separate tables, which can significantly increase loading speed on multicore systems. In the old version, loading a database with 150 million rows on a 10-core processor took 91 seconds, and in the new version, it takes 17 seconds.

There are two ways to load: with or without order preservation.

The fast static symbol table is used for data compression and allows you to pack data into rows using a common type-matching dictionary.

The test database was reduced from 761 MB to 251 MB thanks to the new algorithm.

The Chimp and Patas are proposed to be used to compress numbers.

Chimp has a higher level of compression and faster decompression than the previous gorillas. Chimp is more efficient in terms of compression, but the Patas is more efficient in terms of speed.

The ability to load data fromcsv files in multiple parallel streams was added to the experiment, which reduces load time for largecsv files.

When the option was enabled, the download time for a 720MB file was reduced from 3.5 seconds to 0.6 seconds.

Tics are uncontrollable muscle movements that occur in a repetitive, irregular motion. Motor tics can present in various parts of the body, while vocal tics manifest through throat clearing, sniffing, grunting, and other repetitive sounds.

Nervous tics, on the other hand, are repetitive non-rhythmic, involuntary movements or sounds that occur in sudden bursts. Nervous tics are to be distinguished from nervous habits, such as biting your fingernails, which can be a response to anxiety.

There are three components of spatial resolution:

FOV, or Field of View, is the largest area that your thermal imaging device can "see" at a set distance, and is defined by the lenses horizontal degrees by vertical degrees. E.g 45º x 34º. Note: the "degree" values are units of angular measurement, not degrees of temperature measurement. The image that your camera presents is built up of pixels which corresponds to your cameras thermal resolution E.g 16x16, 320x240, 640x480 etc.

IFOV, or Instantaneous Field of View, is the smallest detail within the FOV that can be detected or seen at a set distance. Instantaneous field of view or (IFOV) is an important calculation in determining how much a single detector pixel can geometrically resolve or "see" in terms of field of view (FOV).

MFOV (also known as IFOVm or measurement resolution), describes the spatial resolution for measurement and is simply the smallest detail that your infrared camera can accurately measure at a set distance. As a thermographer, it critical to understand that as the distance from the target object increases, the ability to accurately measure the temperature of the target is decreased.

Putting it all together.

Imagine you are driving down the highway. Think of the view from your windscreen as the Field of View (FOV). As you drive along you see a sign in the distance. You can "see" the sign but you can't "read" the writing on it because you're still too far away. Think of this as the Instanteneous Field of View (IFOV). As you continue to drive towards the sign you can now "read" the words, or in terms of thermography, "measure" the temperature. This is your Measurement Field of View (MFOV), and is the minimum distance you can accurately measure a temperature at a set distance.

If the target object is too small, or if you're too far away, you really only have three options:
