Example: hash cond(tmp.a=tmp1.b). hash key: the key that is used for hash calculation in multiple shards. In most cases, the key indicates the key of GROUP BY. During a hash join, you need to check whether the table with a small amount of data is used to create a hash ...
In engineering, the kind of pulley I've been describing here is sometimes called ablock and tackle: the wheels and their mounts are the blocks and the ropes that loop around them are the tackle. In my examples, one block is fixed at the top and the other block moves up with the load...
The TCR integrates forces in its triggering process upon interaction with pMHC. Force elicits TCR catch-slip bonds with strong pMHCs but slip-only bonds with weak pMHCs. We develop two models and apply them to analyze 55 datasets, demonstrating the models’ ability to quantitatively integrate and...
This is a trivial example, but if you take a s/coll-of (or any of s/every variants), which can return a myriad of preds depending on how failure happened, this will return very fine grained error message that pin-points exactly how the value failed. This is also very handy for more...

In Europe, for example, the European Union has strict restrictions on how data can be moved in bulk from one country to another or shared by companies like Google that have multiple subsidiaries operating across countries and continents. While Internet-based cloud computing makes national boundaries...

However, in order to understand the age estimation error by reader, multiple independent age estimates should be carried out before marking. In conclusion, this study suggested that the sex ratio bias in the catch of butterfly kingfish was representative of the natural sex ratio in a population ...
This will show us the query plan. It is often the first thing you want to look at when a query is slow because it will show how much data ClickHouse is reading from disk. For example, imagine two MergeTree tables, each with 1 billion rows, one unsorted and one sorted: ...
