* parallel initialization of tiers * do not spawn multiple dbengine event loops * user configurable dbengine parallel initialization * size netdata based on the real cpu cores available on the system netdata runs, not on the system monitored * user configurable system cpus * move cpuset parsing to os.c/.h * fix replication of misaligned chart dimensions * give a different path to each tier thread * statically allocate the path into the initialization structure * use aral for reusing dbengine pages * dictionaries uses ARAL for fixed sized values * fix compilation without internal checks * journal v2 index uses aral * test to see judy allocations * judy allocations using aral * Add config option to select if dbengine will use direct I/O (default is yes) * V1 journafiles will use uv_fs_read instead of mmap (respect the direct I/O setting) * Remove sqlite3IsMemdb as it is unused * Fix compilation error when --disable-dbengine is used * use aral for dbengine work_cmds * changed aral API to support new features * pgc and mrg aral overheads * rrdeng opcodes using aral * better structuring and naming * dbegnine query handles using aral * page descriptors using aral * remove obsolete linking * extent io descriptors using aral * aral keeps one last page alive * add missing return value * added judy aral overhead * pdc now uses aral * page_details now use aral * epdl and deol using aral - make sure ARALs are initialized before spawning the event loop * remove unused linking * pgc now uses one aral per partition * aral measure maximum allocation queue * aral to allocate pages in parallel * aral parallel pages allocation when needed * aral cleanup * track page allocation and page population separately --------- Co-authored-by: Stelios Fragkakis <52996999+stelfrag@users.noreply.github.com>
