orbiter 0a3ab7da1b do not sort concrrently the same array

orbiter d13103a0a7 changed the way how the index cache is flushed: do not flush when a put was made because that could cause that many put calls synchronize for a long time when the dump or a merge is performed. Instead a watchdog thread is doing the dump and therefore puts cannot block any more which is good when a put happens during a search result preparation.

orbiter 1912d0cccc changed handling of RowSet element retrieval: until today all elements had been copied from the underlying byte[] arrays into a new Entry object that again had a copy of a portion of that byte[] in its own bye[]. There was an option to just refer to the underlying byte[] with a pointer but that was almost never used. This commit now changes an interface to the Row class where it is now necessary to tell if a copy is always required. Fortunately the copy is only needed in very rare cases. That means that this change should cause much less memory allocation; it is expected that this happens especially during search situations.

low012 3b40b98256 *) set SVN properties
14 years ago
orbiter cb1f49d0f2 replaced all 'new String' with default encoding (missing) or UTF-8 encoding with a String generation method that uses a pre-defined Charset constant for UTF-8. This avoids a cache-lookup for the Charset object using String hashing of the String 'UTF-8'.
