----------------------------------
Summary: Create sessions in the shard servers to store indexreader
between calls
Key: BLUR-101
URL: https://issues.apache.org/jira/browse/BLUR-101
Project: Apache Blur
Issue Type: Sub-task
Affects Versions: 0.1.5
Reporter: Aaron McCurry
Fix For: 0.1.5
Make use of the TServerEventHandler in Thrift that can give you sessions tied
to Thrift connections. In the every call to Thrift always reset the
IndexReaders in the session except for when a query is followed by a fetch with
locationIds happens. That's when the controller issues a query then after it
has the top answers from all the shards in the table are calculated, it fetches
the data.
The reason we need to do this is because in between those 2 calls the
indexreader could have been refreshed from the writer, and thus the lucene doc
ids could changed. This could cause the fetch to fetch the wrong data back to
the controller.
