When you view execution plans of hash join operations, you also need to focus on the child nodes. hash cond: the join condition. 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...
Explain different types of basic algebra operations with an example. Let g (x) be the inverse of f (x) = x^3 + 2 x + 2. Calculate g (5) (without finding a formula for g (x) ) and then calculate g'(5). Let g (x) be the inverse of f (x) = (x^3) + 4 x + 5. ...
Sorts are expensive operations especially on large tables where the rows do not fit in memory and spill to disk. By default sort blocks are placed into the buffer cache. This may result in aging out of other blocks that may be reread by other processes. To avoid this you can use the pa...

The gateway can potentially match two different dial-peers based on this header. Dial-Peer 1 based on the user portion and dial-peer 2 based on the host portion. However, since a host match is a preference over a user match, dial-peer 2 is used for the inbound dial-pe...
