[mkgmap-dev] [Partch v2] reduce peak memory usage for global index

Hi Thomas,

the jar needs libraries. To run it, you must replace the original mkgmap.jar (or rename that first)

Hi all,

attached is an improved version which also implements the new option --x-mdr7-excl.
It also has some debug messages which will print Strings which appear very often, something like this:
Street index (Mdr7) 'Service' : 11.09%
Street index (Mdr7) 'Straße' : 7.09%
Street index (Mdr7) 'CyW' : 1.66%
Street index (Mdr7) 'Pth' : 3.81%
Street index (Mdr7) 'Weg' : 1.13%
Street index (Mdr7) 'Foot' : 9.17%
Street index (Mdr7) 'Steps' : 1.58%
(sample from Arndts "Speichenkarte" style which adds osm tags to the street name.

The idea is to use Option --x-mdr7-excl="Service,Straße,Foot,Pth" to exclude some strings from the global index.
This will esp. reduce heap memory usage , but it will also reduce the size of the index.

The search will still find roads like "Abc Straße" when you search for abc, but it will not display all the streets containing
Straße when you just type Straße. It should also still display "Straße des 17. Juni" if you type
"Straße des" or just "Juni" in case you use --x-split-name-index.

The binary is here:
