Log Message:
optimizations for NFI XIRAF use case -- thanks a great bunch Jan R.!!
- ds_link (already in Stable) optimized for 1-node case
- indices now contain all data (but still not used automatically, nor based on
Lefteris' new indexing schemes)
most prominently though is: subexpression result caching
- caching hints in pragmas
- query enclosed in (# pf:session id:msec ) { query } or (# pf:session-use
id:msec ) { query }
+ queries in the same session use the same working set (documents opened only
once)
+ same working set allows to cache results
+ pf:session-use only uses cache, cannot add to it
- but, multiple pf:session-use can run concurrently; whereas pf:session is
exclusive
- inside a query, an arbitrary number of expressions can be marked up for
caching/reuse
+ (# pf:cache id ) { subexpr }
+ subexpr may not be enclosed by a for-loop
