In that case, it might make sense for you to use the OS as your database. Divide your tables/rows in some manner and create a hashed directory scheme to save them. So for instance, tables with a 64-bit index that in hex looks something like: "0a924b233f2917fa" would be stored in the directory:
with the fields as files. Or the entire table can be a file (the last path element).
Either way, table management becomes a bit easier, and the OS handles the efficient management of data location and juggling. All you have to do is keep track of how many files can in be in memory at once. But again, can let the OS do that for you, since it will buffer files very efficiently.
Hi,
I am trying to import 22 .dmp files but facing the problem with the last table file it never ends the import command, only the table is created but the rows of the table don't get imported.
This is the problem with only ine table rest 21 tables are being imported properly.

Hi,
I'm wondering if there's a way to dump the content of an array into a specified part of a file.
I know that I can redirect the output in a way that the array adds in the text file, this is done with ">>", but doing by this way, puts the array at the end of the file, and I'm asking for some... (3 Replies)

Hi guys,
I would like to ask your opinion about my theory, how to fix my broken LVM without risking any data loss.
I use Archlinux at home. I just love this distro, even it gives me a lots of work (particularly after system updates).
Basic system spec:

I've never seen this, is it normal for 11.2? Anyway to change it back to dumping metadata or is this simply an overly verbose message I may ignore?

I need a hint about gvfsd-metadata using mate on bsd. Or dual-core cpu, quad-core cpu ore an old laptop single core, the gvfsd is an obstacle and does not accelerate anything, vice versa, it slows down many processes, coming from gnome.

Font::TTF::Ttc(3pm) User Contributed Perl Documentation Font::TTF::Ttc(3pm)NAME
Font::TTF::Ttc - Truetype Collection class
DESCRIPTION
A TrueType collection is a collection of TrueType fonts in one file in which tables may be shared between different directories. In order
to support this, the TTC introduces the concept of a table being shared by different TrueType fonts. This begs the question of what should
happen to the ' PARENT' property of a particular table. It is made to point to the first directory object which refers to it. It is
therefore up to the application to sort out any confusion. Confusion only occurs if shared tables require access to non-shared tables.
This should not happen since the shared tables are dealing with glyph information only and the private tables are dealing with encoding and
glyph identification. Thus the general direction is from identification to glyph and not the other way around (at least not without
knowledge of the particular context).
INSTANCE VARIABLES
The following instance variables are preceded by a space
fname (P)
Filename for this TrueType Collection
INFILE (P)
The filehandle of this collection
The following instance variable does not start with a space
directs
An array of directories (Font::TTF::Font objects) for each sub-font in the directory
METHODS
Font::TTF::Ttc->open($fname)
Opens and reads the given filename as a TrueType Collection. Reading a collection involves reading each of the directories which go to make
up the collection.
$c->read
Reads a Collection by reading all the directories in the collection
$c->find($direct, $name, $check, $off, $len)
Hunts around to see if a table with the given characteristics of name, checksum, offset and length has been associated with a directory
earlier in the list. Actually on checks the offset since no two tables can share the same offset in a TrueType font, collection or
otherwise.
$c->DESTROY
Closees any opened files by us
BUGS
No known bugs, but then not ever executed!
