[geomesa-users] Possible problems and issues re updating from 1.2.1 to 1

[Benjamin Weaver <Benjamin.Weaver@xxxxxxxxxxxxxxxxxx>]

Hi all,

We would like to identify the problems and issues we are likely to face when we upgrade from Geomesa 1.2.1 to 1.3.0. I ask our biggest questions below, but would greatly appreciate information about any other problems you know of.

1. Will our existing data, ingested via geomesa 1.2.1, work correctly in 1.3.0? By 'work' I mean can we query this data properly, and will this older data set be fully co-functional and compatible with data ingested via 1.3.0?

Some context: Our largest and most important table defines a single feature (~40 billion records and growing), and uses an additional attribute index (full) one 1 of our own fields, a 'uuid'.

1a. Do the indexing strategies of the two geomesa versions differ?  (I notice that 1.2.1 creates both [featurename]_z3 and an st_idx indexes). Are featureIDs created in the same way?

2. Will CQL queries yield the same results in 1.3.0 (assuming the same data and query string)?

3. What are the major differences in API that will bear on our ingest and query of data in 1.3.0?

4. 1.2.1 uses java.util.Date. Does 1.3.0 use joda DateTime classes? If so, what bearing does this difference have on date handling in the later geomesa version?

[any and all comments and perspectives are welcome. Our apologies in advance if necessary--we could not just now reach the geomesa archives to consult possible previous answers to my questions] 

Thank you in advance,

Ben Weaver
