Hi Alan,
Solr can do this fast and easy, but I wonder if a simple key-value-store
won't fit better for your suits.
Do you really only need to query be chart_id, or do you also need to
query by time range?
In either case, as long as your data fits into an in-memory database, I
would suggest
Sax is attractive, but I have found it lacking in practice. My primary
issue is that in order to get sufficient recall for practical matching
problems, I had to do enough query expansion that the speed advantage of
inverted indexes went away.
The OP was asking for blob storage, however, and I thi
Definitely should be possible. As an aside, I've also thought one could do
more time series stuff. Have a look at the iSax stuff by Shieh and Koegh:

you are proposing. With a classic RDBM, we hit serious performance issues
so, we moved to solr to display time series of data. The 'trick' was to
facet on a date field, to get 'counts' of data for a time series on a
