deltadb_select_complete(1)

NAME

deltadb_select_complete - command line tool that removes objects from a stream of delta logs (standard input), but keeps the format the same.

SYNOPSIS

deltadb_select_complete [arguments]

DESCRIPTION

deltadb_select_complete is a tool to remove objects from the log. The conditions defined in the arguments are evaluated for all updates, and if the result is ever false, no portion of the object is streamed to the output. This requires a double pass of the data, once to evaluate whether to include each object, and a second time to stream the result. deltadb (prefix 'deltadb_') is a collection of tools designed to operate on data in the format stored by the catalog server (a log of object changes over time). They are designed to be piped together to perform customizable queries on the data. A paper entitled DeltaDB describes the operation of the tools in detail (see reference below).

ARGUMENTS

arguments Any number of arguments of the form with no spaces in between such as: type=wq_master.

EXAMPLES

To include wq_master or chirp history data:
% deltadb_select_complete type=wq_master type=chirp
To include only wq_master history running version 3.7.3:
% deltadb_select_complete type=wq_master | \\
% deltadb_select_complete version=3.7.3
To see full results using a chain of multiple deltadb tools:
% deltadb_collect /data/catalog.history 2013-02-1@00:00:00 d7 | \\
% deltadb_select_static  type=wq_master | \\
% deltadb_reduce_temporal m15 workers,MAX task_running,MAX tasks_running,MAX | \\
% deltadb_reduce_spatial name,CNT workers.MAX,SUM task_running.MAX,SUM tasks_running.MAX,SUM | \\
% deltadb_pivot name.CNT workers.MAX.SUM task_running.MAX.SUM tasks_running.MAX.SUM
