In Presto, we support the popular but non-standard IF construct as a shorthand for CASE, so you can do this: sum(if(bar, foo)) We also have a count_if() function: count_if(bar) http://prestodb.io/docs/current/funct

The screenshot shows it crashing on a method named "semaphore_wait_trap", so that does indeed seem to be an intentional trap for calls that can block the main thread.

The Frontier gate check fee seems to only apply to items that are not eligible to be carry-on. It would not make sense to charge to gate check a carry-on item (as you are often required to do when the overhead bins are full). http:/&#

This uses SQLite virtual tables with a substantial amount of native code, so I imagine getting the existing SQLite JDBC drivers that rely on JNI would be a lot of work. Using a client/server model would probably be easier, though I hav

That is a great idea, but unfortunately triggers are not supported for SQLite virtual tables. You could achieve the same thing by periodically running a query to check for such conditions. This is a common way to build alerting systems.

This is built on SQLite virtual tables, so it didn't require writing a new SQL engine (which is a monumental task): http://www.sqlite.org/vtab.html

You handle this by modeling the account as a ledger with immutable entries containing unique identifiers rather than a single mutable balance. The ledger entries are facts. The balance is a derived computation. Only store facts, not derived

I sent patches in for curl about 10 years ago to switch from select to poll to get around the 1024 FD limit (which was a problem for multi-threaded servers that handled many sockets).
