Re: [geomesa-users] how do you upgrade the catalog if you are upgrading

[Emilio Lahr-Vivaz <elahrvivaz@xxxxxxxx>]

Hi Diane,

1. No, the old caveats still apply - your data will not be modified, just the way we store the metadata in the catalog table. Updating the data is left up to the user, via the index update jobs, as many users have large amounts of data and don't want to re-write it all.
2. You can still manually append new attributes to a schema by modifying the catalog metadata, and any new or updated records will have that attribute. Old data will be null for that attribute.

Is your confusion about adding new attributes to an existing schema? We don't have any documentation for that at the moment, as it's an 'unsupported' feature. I can explain the steps here if that's what you're asking about.

Thanks,

Emilio

So it took me a bit to understand the terminology.  In the 1.2.4 release notes you mention once you upgrade to 1.2.4 one cannot revert a catalog back to 1.2.3 or older without doing some manual steps which you all can provide.

 

So that begs the following questions:

 

1.       Can one upgrade an existing catalog that maybe was created in version 1.2.0, 1.2.2, or 1.2.3 to an newer version and get any indexing improvements without dropping and re-ingesting?

2.       Can one update the catalog to have new fields (i.e. add a second geometry or just new ifelds) and then any new ingests of the existing records as well as new records will fill out those new columns? 

 

I understand now how to manually update one of the rows in the catalog now but many of the rows are related and as I can see from schemas when I ingested under 1.2.0 and 1.2.3 that the attributes row looks different depending on the geomesa version I created the simple feature attribute type with.

 

So I am not sure if I can upgrade an existing simple feature type/catalog or how to do it. 

 

Any explanation or pointer to an area of the documentation would be appreciated.

 

Diane
