Pavel Tupitsyn commented on IGNITE-3325:


* CompiledQuery class deprecated
* CompiledQuery2 class added with all the same methods, but taking 
Expression instead of raw Func<>. For most use cases the transition will 
not require code changes.
** Fixes Skip/Take and similar issues
** Allows embedded arguments (specify constant literals directly, e.g. .Where(x 
< 5))
** Allows using the same argument multiple times
* Compile(IQueryable query) overload added
** Allows any number of arguments
** Allows compiling existing queries (no requirement to provide an expression)
** Allows "query builder" pattern where LINQ expression is constructed step by 
step
