-### How to choose `m` and `ef_construction` for `IVF_HNSW_*` index?
-
-`m` determines the number of connections a new node establishes with its closest neighbors upon entering the graph. Typically, `m` falls within the range of 5 to 48. Lower `m` values are suitable for low-dimensional data or scenarios where recall is less critical. Conversely, higher `m` values are beneficial for high-dimensional data or when high recall is required. In essence, a larger `m` results in a denser graph with increased connectivity, but at the expense of higher memory consumption.
-
-`ef_construction` balances build speed and accuracy. Higher values increase accuracy but slow down the build process. A typical range is 150 to 300. For good search results, a minimum value of 100 is recommended. In most cases, setting this value above 500 offers no additional benefit.

+This section provides a set of recommended best practices to help you get the most out of LanceDB Cloud. By following these guidelines, you can optimize your usage of LanceDB Cloud, improve performance, and ensure a smooth experience.
+
+### Should the db connection be created once and keep it open?
+Yes! It is recommended to establish a single db connection and maintain it throughout your interaction with the tables within. 
+
+LanceDB uses `requests.Session()` for connection pooling, which automatically manages connection reuse and cleanup. This approach avoids the overhead of repeatedly establishing HTTP connections, significantly improving efficiency.
+
+### Should a single `open_table` call be made and maintained for subsequent table operations?
+`table = db.open_table()` should be called once and used for all subsequent table operations. If there are changes to the opened table, `table` always reflect the latest version of the data. 
+
+### Row id
+
+### What are the vector indexing types supported by LanceDB Cloud?
+We support `IVF_PQ` and `IVF_HNSW_SQ` as the `index_type` which is passed to `create_index`. LanceDB Cloud tunes the indexing parameters automatically to achieve the best tradeoff betweeln query latency and query quality.
+
+### Do I need to do anything when there is new data added to a table with an existing index?
+No! LanceDB Cloud triggers an asynchronous background job to index the new vectors. This process will either merge the new vectors into the existing index or initiate a complete re-indexing if needed. 
+
+There is a flag `fast_search` in `table.search()` that allows you to control whether the unindexed rows should be searched or not.

+LanceDB Cloud supports **vector index**, **scalar index** and **full-text search index**. Compared to open-source version, LanceDB Cloud focuses on **automation**:
+
+- If there is a single vector column in the table, the vector column can be inferred from the schema and the index will be automatically created. 
+
+- Indexing parameters will be automatically tuned for customer's data.
+
+## Vector index
+LanceDB has implemented the state-of-art indexing algorithms (more about [IVF-PQ](https://lancedb.github.io/lancedb/concepts/index_ivfpq/) and [HNSW](https://lancedb.github.io/lancedb/concepts/index_hnsw/)). We currently

+## Scalar index
+LanceDB Cloud and LanceDB Enterprise supports several types of Scalar indices to accelerate search over scalar columns.
+
+- *BTREE*: The most common type is BTREE. This index is inspired by the btree data structure although only the first few layers of the btree are cached in memory. It will perform well on columns with a large number of unique values and few rows per value.
+- *BITMAP*: this index stores a bitmap for each unique value in the column. This index is useful for columns with a finite number of unique values and many rows per value. 
+    - For example, columns that represent "categories", "labels", or "tags"
+- *LABEL_LIST*: a special index that is used to index list columns whose values have a finite set of possibilities. 
+    - For example, a column that contains lists of tags (e.g. ["tag1", "tag2", "tag3"]) can be indexed with a LABEL_LIST index.

-* `m`: The number of neighbors to select for each vector in the HNSW graph.

-## Handling bad vectors
-
-In LanceDB Python, you can use the `on_bad_vectors` parameter to choose how
-invalid vector values are handled. Invalid vectors are vectors that are not valid
-because:
-
-1. They are the wrong dimension
-2. They contain NaN values
-3. They are null but are on a non-nullable field
-
-By default, LanceDB will raise an error if it encounters a bad vector. You can
-also choose one of the following options:
-
-* `drop`: Ignore rows with bad vectors
-* `fill`: Replace bad values (NaNs) or missing values (too few dimensions) with
-    the fill value specified in the `fill_value` parameter. An input like
-    `[1.0, NaN, 3.0]` will be replaced with `[1.0, 0.0, 3.0]` if `fill_value=0.0`.
-* `null`: Replace bad vectors with null (only works if the column is nullable).
-    A bad vector `[1.0, NaN, 3.0]` will be replaced with `null` if the column is
-    nullable. If the vector column is non-nullable, then bad vectors will cause an
