Hi,
I am working on an embedded application using SQLite.
My lookaside configuration:
sqlite3_db_config(mydbhandle,
SQLITE_DBCONFIG_LOOKASIDE,
0,
64,
128);
After doing some profiling, I saw that sqlite3DbMallocRaw does not allocate
from the lookaside
buffer pool even when the sizes match.
The reason is, that all available lookaside places are used for prepared
statements during application
startup.
For my understanding, this should not!
I added a simply possibility for disabling the allocation from the lookaside
pool temporally.
This is controlled by my application during static statement preparation
and enabled afterwards using this added db_config call:
sqlite3_db_config((sqlite3*) db, SQLITE_DBCONFIG_DISABLE_LOOKASIDE, 1);
This small change, keeps the lookaside pool mostly unused, and it is available
to serve many small
allocations during normal operation.
My Question:
Is there a way for disabling the use of lookaside buffers for prepared
statement handles?
Regards
Maik Scholz
