You can use the Google Cloud console to create and manage aggregate column families for your Bigtable tables. You can also view and query aggregate column families in Bigtable Studio. This feature is generally available (GA). For more information, see Create and manage tables and Manage your data using Bigtable Studio.

You can use the allow_incomplete_view query hint in SQL queries to read data
from a continuous materialized view before its initial population finishes. This
feature is generally available (GA).
For more information, see Read data during initial population.
August 12, 2026
You can use parameterized views in Bigtable to dynamically filter data ranges for logical views based on application context and mitigate SQL injection risks. This feature is generally available (GA). For more information, see Parameterized views overview.
You can use the CLUSTER_ATTRIBUTE() filter to restrict continuous materialized
view processing to specific clusters. This function lets you isolate views
within an instance. This feature is generally available (GA).
For more information, see Non-deterministic SQL functions.

Performance Improvements
July 30, 2026
You can use Bigtable as a remote storage backend for LMCache. By storing the large language model (LLM) key-value (KV) cache externally in Bigtable, multiple AI serving instances can share and reuse precomputed attention tensors. This reduces compute overhead and significantly improves time-to-first-token (TTFT) for repeated prompts and shared documents. This feature is in Preview.
July 29, 2026
You can use the Google Cloud console to manage row key schemas for your Bigtable tables. This feature is in Preview.
July 27, 2026
The Bigtable remote MCP server supports the Bigtable Data API, which
provides the execute_sql tool that you can use to query Bigtable data using
natural language prompts. This feature is
generally available (GA).
