Hello,
It looks like i might have run into a bug in Firebird version 2.5.3
(also 2.5.2).
I have databases with ON CONNECT trigger that load some context values
from a table. However, some times the context values appear to have not
been loaded (or loaded and lost?). I am absolutely sure the
GFIX fails to output in my app but outputs nicely in CMD screen

Hi Jim,
I made some research about storage compresion and I found this project:
https://code.google.com/p/lz4/
My idea is to use this only if encoded size of record will be more than
aprox 4Kb.
Do you have any note, why it can be bad idea?
Thanks Slavek
PS: I was made some changes in
The main blocker for switching to firebird as base backend is
firebird data format endianess.
The main remaining issue is that the firebird data format embedded in the
.odb file is endianess-dependent. The idea is to switch to Firebird's
archive format that is not.

Using Firebird in office siute was a bad idea from the beginning. No matter

I'd like to see some numbers computed from an actual (real) Firebird
database before it is considered.
But why records only over 4k? And what commonality do you expect to find
on large records?

Test with tpcc.fdb using lz4 command line (not most realistic sample in
the world, but hopefully more or less OK).
DB file is 211864K, after
How you are declaring it in the record?
You should use ISC_QUAD.
Adriano
I use Int64 it is equivalent to ISC_QUAD
but I see what hapened
Whe should decide about buffer alignment
I can use packed record instead of record then data are as is
But what is your buffer alignment when you fill data in
Hi Adriano,
I'm using Firebird for a long time.
I decided that I could do something more for the Firebird community.
I started working on support for all types supported by the Firebird in your
FB Api on Delphi.
And so I now have the following types of operating correctly:
-Integer,
-Date,

It's really Int64. ISC_QUAD is for blobs.

Hello again,
After further investigation, it turns out the problem is NOT with
context values getting lost but rather in the ON CONNECT database
trigger not firing when connecting. Furthermore, so far it has always
been the SECOND attachment to the db (by attachment id) after OS restart

Hi Jim,
I have only my DBs, that is designed for short record length (on disk).
I looking for some real examples, but is not easy to get it.
Some data from my DB (new RLE):
Primary pointer page: 384, Index root page: 385
Total formats: 1, used formats: 1
Average record length: 31.20,
Hi Karol,
in current simplified stack you have:
execution engine
record level compresion
page storage
cache
hdd
On small records, you have CPU problem, but on large records you can
simply utilize HDD.
To utilize HDD tou have to meet at least ~200MB/s on common CPU.
Target is: be able utilize
The oroblem with that technique is that lz4 get getting credit fir
compression of partially empty data and index pages and tips and space
utilization pages that have predictable repeating content.
There's really no way to estimate the effective compression other than to
code it up and try it.

IIRC, it was temporarily disabled one day due to Windows build issues
and supposedly forgotten to be enabled back. I will check.
