* Set a flag to do aclk sync thread shutdown Attempt to dequeue a cmd in case the queue is full and someone is blocked * Drop tables and recreate instead of deleting * Add commands to check the database -W check-database, fix-database, compact-database * Split the database setup to config and cleanup part * Add checks during database setup and cleanup to detect corruption to the dimension and chart tables * Add full database check and refactor code * Change commands to better indicate that the operations refer to the sqlite metadata database (not the metrics dbengine database) * Add check for table being null (request for entire database check) * Rename command for better clarity
