Hello, I am using sqlite in an embedded environment with very limited memory. In an attempt to reduce memory consumed by sqlite, I am executing PRAGMA cache_size=new_size and PRAGMA default_cache_size=new_size upon opening all of my db's, which are both file based and in-memory. I have varied the value of new_size from 2000 (default), to 1000 to 500 to 0 and none of these values seems to lower the amount of memory sqlite consumes.
I have verified the new cache size settings were registered in the db's using PRAGMA cache_size. I then verify sqlite memory usage with the sqlite3_status() functions, which do not show a change in return value for SQLITE_STATUS_PAGECACHE_OVERFLOW or SQLITE_STATUS_MEMORY_USED (around 7.9MB and 8.2MB respectively) I have not changed the default memory allocation (ie no scratch, cache or heap memory allocation at startup). I have configured sqlite3_soft_heap_limit(8192000). Any help in figuring out how to limit the cache usage of memory would be appreciated. -- thanks, ed _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
