Michael Hackstein 1afd19e550 Fixed the resizing of AssocUnique. It was different from AssocMulti which cased the nonUnique index to be faster than the unique one 2015-09-08 11:48:57 +02:00
Michael Hackstein 481cb1b7dd Removed const in AssocMulti batch insert. It was non-const casted internally... 2015-09-03 10:16:15 +02:00
Michael Hackstein 9001e88a89 Added a general batch inserter for AssocUnique. Not used in any index yet 2015-09-03 10:16:14 +02:00

Max Neunhoeffer c0f1b72bab Add "sensible" madvise calls. 
Essentially the strategy is: A newly created and a newly opened file
is advised to be "SEQUENTIAL ACCESS", because we will either write to
it or scan it sequentially. As soon as it is sealed, we switch the
advice to "RANDOM ACCESS", because this should be the normal pattern and
aggressive read-aheads tend to be bad. The collector and the compactor
switch a sealed file back to "SEQUENTIAL ACCESS" just before they scan
it and back to "RANDOM ACCESS", when they are done.

Furthermore, all data files in a collection are advised with "WILLNEED"
just before the collection is scanned during loading.

Finally, the actual hash table of AssocMulti is advised to be random
access, although this is an anonymous map given to us by malloc and not
a memory mapped file.
