Abstract
The control system of the X-ray complex LIA-20 is based on the Tango Controls framework. Data archiving subsystem HDB++ was improved during the work for efficient storage of waveforms. PostgreSQL DBMS support as a storage was added. PostgreSQL extension “pguint” for unsigned numbers support was modified to support the binary transfer mode during this work. Performance testing of the modified “pguint” extension and the new DBMS interface was performed. This solution allowed to significantly increase the performance of HDB++, reduce the amount of data stored in the database, as well as remove restrictions on the size of the stored data.
