2022-01-17 Search and Sort Cache Statistics

Service Stack - Search and Sort

Overview

• Want to be able to see how often complexFilter/SearchResult/SortResult (search stage) hits cache

Store statistics

• Dynamo table
• partition key: search stage tag
• sort key: start timestamp

Parents record children

• Also store for each record a list of child search stages
• Maybe just immediate ones, and they store theirs etc, making a graph of child stages

Correlation id

• Similar to debug logging want to add a correlation id that sets whether recording statistics
• Have an environment variable that sets chance of recording statistics
• Could tie into log level, eg if log level is DEBUG then always record statistics

Monitoring time spent

• add in timestamps for each search stage so can monitor how long they take
• Perhaps timestamp when starts and timestamp when ends

Checks in code

• try to tie into existing functions, but might need to add additional functions when starting the request and completing it
• might need another function that triggers when sending to a child search stage, for the parent to record it
