KVDB and TableDB

Besides device control, XXTLanControl includes two built-in data tools that you can manage directly from the UI: KVDB and TableDB.

KVDB​

KVDB is good for lightweight shared state. It contains two structures:

  • queue: useful for task delivery, consumption order, and waiting lists
  • dict: useful for configuration, flags, counters, and shared variables

The KVDB manager currently supports:

  • creating, renaming, and deleting queues or dictionaries
  • queue push, pop, clear, value-based removal, and counting
  • dictionary write, copy, move, increment, delete, and read-all
  • full backup and restore

If your scripts or schedules need to read the state stored here, you can also use it through LCC.kvdb.

TableDB​

TableDB is good for structured tabular data such as account lists, run results, and other business data.

The TableDB manager currently supports:

  • creating new tables
  • editing table schema
  • adding, editing, and deleting rows
  • truncating or deleting tables
  • sorting, searching, and paginated browsing
  • per-column statistics
  • single-table import and export in JSON, CSV, and XLSX
  • full backup and restore

If your scripts or schedules need to read or write these tables, you can continue using them through LCC.db.

When to Use Which One​

  • Use KVDB for simple state, counters, and queues
  • Use TableDB for structured records, import/export, filtering, and sorting
  • If your workflow uses both scripts and schedules, choose by data shape: state and queues fit KVDB, while tabular business data fits TableDB
