Performance improvements and bug fixes

Bug fixes in queries performing boolean searches

SELECT * FROM ds.collection where col1 = true would fail before this version due to incorrect handling of boolean constants

This release also contains improvements in aggregate operations such as SUM and AVG. The result of aggregate was inconsistent due to incorrect thread concurrency management.

Bug Fixes:

• [RESOLVED] Problem with transaction management at high concurrency, causing undesired thread locking

• Default timeout of 60 seconds for DML and 300 seconds timeout for read operations
• Changed default setting of QueryPerformanceAnalysis to disabled
• Control to disable Tableau operations when a Tableau is not connected
• Set max heap size to -Xmx128G. It is not recommended to have more than 128G memory on a single instance.
• Resolution for ISSUE #3
