My "first is worst" suggestion would be to create a .vrt for each day:
gdalbuildvrt Day1.vrt [date]*.tif
gdalbuildvrt Day2.vrt [date]*.tif
...
Next, in your .map file use runtime substitution:
DATA "/file/path/Day%day%.vrt"
If you really want to make this fast, convert all your source .tif's to
format COG. All you tif's will be tiled:
gdalwarp -f COG -co COMPRESS=DEFLATE -co BIGTIFF=YES sent.tif sent_cog.tif

Hello,
up to now, I have been working with VRT as a carrier for the rasters I
wanted to use in the mapfile. Now in order to use the rasters that were
provided to me (they are GCP georeferenced rasters) I have to convert
them to VRT(via gdal warp), hence my question - how can I mosaic the
rasters within one layer in Mapserver (one layer = one day of photos
from Sentinel-2 for example). I can't create vrt to existing vrt, and
creating a tileindex for each layer generates too many files. I wanted
to create one vrt gathering together all of raster but gdal_warp uses
only the first one as data source.
What can I do?
Best regards,
Marcin
