+### Where can I find benchmarks for LanceDB?
+
+Refer to this [post](https://blog.lancedb.com/benchmarking-lancedb-92b01032874a) for recent benchmarks.
+
+### How much data can LanceDB practically manage without effecting performance?
+
+We target good performance on ~10-50 billion rows and ~10-30 TB of data.
+
+### Does LanceDB support concurrent operations?
+
+LanceDB can handle concurrent reads very well, and can scale horizontally. The main constraint is how well the [storage layer](https://lancedb.github.io/lancedb/concepts/storage/) you've chosen scales. For writes, we support concurrent writing, though too many concurrent writers can lead to failing writes as there is a limited number of times a writer retries a commit
+
+!!! info "Multiprocessing with LanceDB"
+
+    For multiprocessing you should probably not use ```fork``` as lance is multi-threaded internally and ```fork``` and multi-thread do not work well.[Refer to this discussion](https://discuss.python.org/t/concerns-regarding-deprecation-of-fork-with-alive-threads/33555)

+### ColBERT Reranker
+This reranker uses the ColBERT model to combine the results of semantic and full-text search. You can use it by passing `ColbertrReranker()` to the `rerank()` method. 
+
+ColBERT reranker model calculates relevance of given docs against the query and don't take existing fts and vector search scores into account, so it currently only supports `return_score="relevance"`. By default, it looks for `text` column to rerank the results. But you can specify the column name to use as input to the cross encoder model as described below.
+
+```python
+from lancedb.rerankers import ColbertReranker
+
+reranker = ColbertReranker()
+
+results = table.search("harmony hall", query_type="hybrid").rerank(reranker=reranker).to_pandas()

+Arguments
+----------------
+* `model_name` : `str`, default `"colbert-ir/colbertv2.0"`
+        The name of the cross encoder model to use.
+* `column` : `str`, default `"text"`
+        The name of the column to use as input to the cross encoder model.
+* `return_score` : `str`, default `"relevance"`
+        options are `"relevance"` or `"all"`. Only `"relevance"` is supported for now.

+
+!!! Note
+    This prompts chat model to rerank results which is not a dedicated reranker model. This should be treated as experimental.
+
+!!! Tip
+    You might run out of token limit so set the search `limits` based on your token limit.

+    The name of the cross encoder model to use.
+`column` : `str`, default `"text"`
+    The name of the column to use as input to the cross encoder model.
+`return_score` : `str`, default `"relevance"`
+    options are "relevance" or "all". Only "relevance" is supported for now.
+`api_key` : `str`, default `None`
+    The API key to use. If None, will use the OPENAI_API_KEY environment variable.

 ## Building Custom Rerankers
 You can build your own custom reranker by subclassing the `Reranker` class and implementing the `rerank_hybrid()` method. Here's an example of a custom reranker that combines the results of semantic and full-text search using a linear combination of the scores.

Will Jones	57605a2d86	feat(python): add `read_consistency_interval` argument (#828 ) This PR refactors how we handle read consistency: does the `LanceTable` class always pick up modifications to the table made by other instance or processes. Users have three options they can set at the connection level: 1. (Default) `read_consistency_interval=None` means it will not check at all. Users can call `table.checkout_latest()` to manually check for updates. 2. `read_consistency_interval=timedelta(0)` means always check for updates, giving strong read consistency. 3. `read_consistency_interval=timedelta(seconds=20)` means check for updates every 20 seconds. This is eventual consistency, a compromise between the two options above. ## Table reference state There is now an explicit difference between a `LanceTable` that tracks the current version and one that is fixed at a historical version. We now enforce that users cannot write if they have checked out an old version. They are instructed to call `checkout_latest()` before calling the write methods. Since `conn.open_table()` doesn't have a parameter for version, users will only get fixed references if they call `table.checkout()`. The difference between these two can be seen in the repr: Table that are fixed at a particular version will have a `version` displayed in the repr. Otherwise, the version will not be shown. ```python >>> table LanceTable(connection=..., name="my_table") >>> table.checkout(1) >>> table LanceTable(connection=..., name="my_table", version=1) ``` I decided to not create different classes for these states, because I think we already have enough complexity with the Cloud vs OSS table references.
