------------------------------------
Summary: Implement script to compare lucene indexes logically
Key: OAK-7122
URL: https://issues.apache.org/jira/browse/OAK-7122
Project: Jackrabbit Oak
Issue Type: Task
Components: run
Reporter: Chetan Mehrotra
Assignee: Chetan Mehrotra
Fix For: 1.8
With Document Traversal based indexing we have implemented a newer indexing
logic. To validate that index produced by it is is same as one done by existing
indexing flow we need to implement a script which can enable comparing the
index content logically
This was recently discussed on lucene mailing list [1] and suggestion there was
it can be done by un-inverting the index. So to enable that we need to
implement a script which can
# Open a Lucene index
# Map the Lucene Document to path of node
# For each document determine what all fields are associated with it (stored
and non stored)
# Dump this content in file sorted by path and for each line field name sorted
by name
Then such dumps can be generated for old and new index and compared via simple
text diff
