azure_queue_metadata

Description

Contains the current number of processed, processing and failed nodes in keeper for each AzureQueue metadata object and, on demand, their contents. Unlike system.azure_queue_metadata_cache, which shows the in-memory cache, this table reads the state directly from keeper.

Columns

• zookeeper_path (String) — Path in zookeeper to metadata. For a queue on an auxiliary zookeeper this is the factory key <zookeeper_name>:<path>, not the raw keeper path.
• processed_nodes_count (Nullable(UInt64)) — Number of nodes in the processed directory in keeper. Only set for unordered mode: in ordered mode there are no per-file processed nodes (see processed_path instead), so the value is NULL.
• processing_nodes_count (UInt64) — Number of nodes in the processing directory in keeper
• failed_nodes_count (UInt64) — Number of nodes in the failed directory in keeper
• processed_nodes (Map(String, String)) — Contents (node name -> node data) of the processed directory in keeper. Only filled for unordered mode. Fetched only when this column is selected.
• processing_nodes (Map(String, String)) — Contents (node name -> node data) of the processing directory in keeper. Fetched only when this column is selected.
• failed_nodes (Map(String, String)) — Contents (node name -> node data) of the failed directory in keeper. Fetched only when this column is selected.
• processed_path (Map(String, String)) — Last processed path per processed pointer in keeper (relative pointer path -> last processed file path). Only filled for ordered mode, where it covers the single, per-bucket and per-partition pointers. Fetched only when this column is selected.
