Problem Note 67955: The hashTblRemove() method removes extra keys from the hash table in SAS® Micro Analytic Service
 |  |  |  |  |
Per the section "Shared Hash Tables" in the SAS® Micro Analytic Service 2.5M3: Programming and Administration Guide:
Shared hash tables in SAS Micro Analytic Service enable high-performance sharing of in-memory, stateful data between modules and across transactions. Shared hash tables consist of key/value pairs, where the keys are strings and the values are state vectors. . . The MASState package contains all the methods that are required for DS2 modules to share data across SAS Micro Analytic Service modules and transaction boundaries.
In addition, you can use a Calculate window in SAS® Event Stream Processing to execute Data Step 2 (DS2) code that uses SAS Micro Analytic Service modules and methods.
One such method is the hashTblRemove() method. Using this method deletes a key that you specify from the hash table. However, it deletes keys that you do not specify as well, which can cause various problems.
