• Since it is possible for the server (i2b2 hive) to take a long time to provide all the data requested, this plugin provides occasional updates of 'Elapsed time' and 'estimated remaining run time', etc. displays while the data are being fetched. These displayed values are at best rough estimates based on occasional data coming back from the server. In the case of zero 'Query Subgroup Size' selected (i.e. no query-subgrouping), then there would be no data coming back from the server until either of the following situations:** The whole, single, query is done.
  • The server itself started paging (i.e. query-subgrouping), and the result of the 1^st of such paged subqueries just arrived.
  • The server got overwhelmed by all the excessive data and failed, returning an 'error'.

In   - Note that in any of these cases, the updates of 'Elapsed time' and 'estimated remaining run time' will be quite infrequent, as updates from the server (i2b2 hive) will most likely take a long time, and     and far and few in-between, if any.
