Database structure

ShedLock

The PowerAuth Server uses ShedLock to synchronize scheduled operations. You need to create appropriate DB table, i.e.:

CREATE TABLE shedlock (
    name VARCHAR(64) NOT NULL PRIMARY KEY,
    lock_until TIMESTAMP NOT NULL,
    locked_at TIMESTAMP NOT NULL,
    locked_by VARCHAR(255) NOT NULL
);

See the SchedLock documentation for the details.

Table Documentation

This chapter explains individual tables and their columns. The column types are used from PostgreSQL dialect, other databases use types that are equivalent (mapping is usually straight forward).
