StreamBase Disk Query Table Upgrade Helper

This utility will help upgrade disk querytables between versions of StreamBase.

1. Update the schemas in gen_disk_qt_upgrade.py __main__ section. The generation methods support upgrading multiple tables in the same app simulatenously.

   1. Update the table definitions

       example_table = { 
           # TableName -> the table to upgrade
           'TableName' : 'NamedPointTable',
      
           # Schema -> the table's schema in ssql form
           'Schema' : '''( 
               x int,
               y int,
               z int,
               name string)''',
      
           # pkey -> comma separated list of fields
           'pkey' : 'name, x',
      
           # skeys -> list of comma separated lists of fields
           'skeys' : ['y, z', 'z']
       }
      

   2. Update the list of tables and container names

       tables = [example_table1, example_table2]
       container = 'table_container'
      

2. run gen_disk_qt_upgrade.py

3. manually start two sbds

   1. the old one should be started with the old version of StreamBase on port 10000

       sbd -p 10000 --datadir data-old
      

   2. the new one should be started with the new version of StreamBase on port 10001

       sbd -p 10001 --datadir data-new
      

4. run the driver.sh shell script

5. wait for the computer to finish computing (this will be quick for small tables)
