Unlimited dimension cannot work without a specified length about netcdf-java HOT 3 CLOSED

I believe isUnlimited means that the dimension has a size but can grow and isVariableLength means the size is not currently known, see here. So perhaps isVariableLength is more what you are looking for?

from netcdf-java.

Actually, let me walk back my last comment a bit-- I don't know if you should use isVariableLength here-- it is usually used as the dimension for a variable that is a "ragged array" (see "VLEN" section here if you are interested).

But regardless, the behavior of isUnlimited that you show is correct-- you need to specify a starting length for the dimension, though it is allowed to grow.

Is it possible to grow the variable after the file is already out of define mode? I'm facing an issue where it's not possible to write an array of 1D data greater than the size of the unlimited variable's initial variable.

Is it expected that we must know the max size of data we need to write (and to set it as the initial value of the unlimited variable) before going out of define mode?
