  1. Queue Performance Tuning

The Results Export Queue is a table in the CM4D Site database that handles the messages coming from the CM4D database(s) before it is sent to the Results services to be processed into the Results database. The row entries in this table may not correlate to individual data files in a 1:1 ratio (e.g. 1 row = 1 sample), but rather sets of information may be grouped as a single entry in the queue.

Nothing should ever be deleted from this table! Doing so can result in lost data and will require you to manually export your entire CM4D database(s) to the Results database. See here for information on keeping CM4D database synchronized with the Results database.

Queue Performance Tuning

The number of results that will be grouped together in the Results Export Queue before they are sent to the Results Services can be adjusted in the defaults section of the Cm4d.ini file. This is really only used for performance tuning. Generally, this number will not need to be adjusted.

Cm4d.ini File Setting:

[defaults]

RESULTSEXPORTBATCHSIZE=1000
