->We are dealing with Flat files and facing relative table is open issue for given below scenario.
->For scenario, when we define more than one table schema in one schema file then query is not giving any result initially it used to give Table is relatively open issue.
->Our application makes use of the driver for concurrent reads with different driver class instances. So , there are basically two read access requests at the same time.
->The issue will be reoccurred only when two separate instances of driver are set to read same table at same time (concurrently).
->To replicate the issue fire query simultaneously on files having schema define d inone single schema file.

Tested again. No issue. % has been supported since March 9th, but disable % as escape character feature.

Tested again with 100~200 concurrent threads. No issue for March 11th version. Your will receive a test sample.

Supported. Because @ is a special character too, and % can not disable fully as escape character feature.
