Delayed Synchronization
The delayed synchronization feature allows you to select how IDOL server synchronizes the index cache with the IDOL server data. This process is useful in systems where you schedule indexing tasks at times when IDOL server is also handling queries.
By default, synchronization occurs as soon as a representation of data has been made in the index cache. New data is available to the user (as query results) quickly, so use this setting in systems where up-to-date data is the priority. However, synchronization uses resources that IDOL server could otherwise use for querying.
Delayed synchronization reduces the impact of this effect by collecting multiple data representations in the index cache and then synchronizing them all with IDOL server's data in one go. This process is useful in systems where query speed is more important than having up-to-date data.
 
NOTE Autonomy recommends using delayed synchronization if you index a lot of small files (files that are smaller than 100MB).
The DelayedSync parameter in the [Server] section of IDOL server's configuration file allows you to specify whether the indexing process uses delayed synchronization.
To configure delayed synchronization
1.
Enter DelayedSync=true if you want IDOL server to delay synchronization. If you set DelayedSync to true, IDOL server stores data on disk only when:

2.
Enter DelayedSync=false if you do not want IDOL server to delay synchronization.
