Avoid reading VERSIONS and DEFAULTS table after it is done once in a process.
This required following cleanup
1. cqd MODE_SEABASE is removed.
2. Removed the support to read CQD from a file.
3. NADefaults constructor now reads the defaults table once and
   saves off the relevant information such as currentDefaults, currentTokens,
   provenances and currentFloats to be reused by the other NADefaults objects.
4. T2 driver doesn't use the defaultContext to compile any query. Hence, it is not
   possible to use the heap from CmpContext to save off the defaults value.
   The code has been changed the heap from CliGlobals to save the current defaults.
5. Fixed code to use static literals as it is from the defaultsDefaults to
   avoid invalid memory in the saved defaults
6. Changes to optimize initialization of currentTokens_ in NADefaults
7. CQD * RESET RESET
   CQD * RESET
   Now resets to the defaults when CQD * RESET RESET was issued.
8. Also optimized initCurrentsFromDefaultsTable further.

Apache Trafodion

trafodion logo

Apache Trafodion is a webscale SQL-on-Hadoop solution enabling transactional or operational workloads on Hadoop. The name “Trafodion” (the Welsh word for transactions, pronounced “Tra-vod-eee-on”) was chosen specifically to emphasize the differentiation that Trafodion provides in closing a critical gap in the Hadoop ecosystem. Trafodion builds on the scalability, elasticity, and flexibility of Hadoop. Trafodion extends Hadoop to provide guaranteed transactional integrity, enabling new kinds of big data applications to run on Hadoop.
