[mapserver-users] Mapcache and partial reseeding

[Rahkonen Jukka]

Hi,

How well does Mapcache seeder tool handle the case when the original big aerial image coverage is updated little by little so that the hole cycle takes 3 to 6 years? Reseeding the whole cache every time when a batch of new images is received does not feel like a reasonable solution. 

A) Can the seeder tool ake a fast delete for all tiles which intersect the update area geometry so that it is guaranteed that outdated tiles are not delivered.  Only high zoom levels (Z greater than X) should be purged. Low zoom levels may stay as they are because they are not used for interpretation.
B) Can the seeding tool reseed those areas?
C) Is the behaviour similar for disk cache and Berkeley DB cache?
