Brian

I you create a CHAR (256) column then the column will always reserve 256
Unicode characters plus a length field, i.e. 256*2+4 = 516 bytes. If you
want variable length strings then use the TEXT type, although this will be
slightly slower.

Subject: InstantDB: Memory consumption and column widths

> I have a fairly large database (a couple of thousand records) and I'd

> If a column is declared as CHAR(256), is InstantDB using that as the
