+# Variable and Secrets
+
+Most embedding configuration options are saved in the table's metadata. However,
+this isn't always appropriate. For example, API keys should never be stored in the
+metadata. Additionally, other configuration options might be best set at runtime,
+such as the `device` configuration that controls whether to use GPU or CPU for
+inference. If you hardcoded this to GPU, you wouldn't be able to run the code on
+a server without one.
+
+To handle these cases, you can set variables on the embedding registry and
+reference them in the embedding configuration. These variables will be available
+during the runtime of your program, but not saved in the table's metadata. When
+the table is loaded from a different process, the variables must be set again.
+
+To set a variable, use the `set_var()` / `setVar()` method on the embedding registry.
+To reference a variable, use the syntax `$env:VARIABLE_NAME`. If there is a default
+value, you can use the syntax `$env:VARIABLE_NAME:DEFAULT_VALUE`.
+
+## Using variables to set secrets
+
+Sensitive configuration, such as API keys, must either be set as environment
+variables or using variables on the embedding registry. If you pass in a hardcoded
+value, LanceDB will raise an error. Instead, if you want to set an API key via

+Many embedding functions that run locally have a `device` parameter that controls

+it's helpful to be able to set the `device` parameter at runtime, rather than
+have it hard coded in the embedding configuration. To make it work even if the

+configuration.
+
+Some embedding libraries even have a method to detect which devices are available,

+# Late interaction & MultiVector embedding type
+Late interaction is a technique used in retrieval that calculates the relevance of a query to a document by comparing their multi-vector representations. The key difference between late interaction and other popular methods:
+
+![late interaction vs other methods](https://raw.githubusercontent.com/lancedb/assets/b035a0ceb2c237734e0d393054c146d289792339/docs/assets/integration/colbert-blog-interaction.svg)
+
+
+[ Illustration from https://jina.ai/news/what-is-colbert-and-late-interaction-and-why-they-matter-in-search/]
+
+<b>No interaction:</b> Refers to independently embedding the query and document, that are compared to calcualte similarity without any interaction between them. This is typically used in vector search operations.
+
+<b>Partial interaction</b> Refers to a specific approach where the similarity computation happens primarily between query vectors and document vectors, without extensive interaction between individual components of each. An example of this is dual-encoder models like BERT.
+
+<b>Early full interaction</b> Refers to techniques like cross-encoders that process query and docs in pairs with full interaction across various stages of encoding. This is a powerful, but relatively slower technique. Because it requires processing query and docs in pairs, doc embeddings can't be pre-computed for fast retrieval. This is why cross encoders are typically used as reranking models combined with vector search. Learn more about [LanceDB Reranking support](https://lancedb.github.io/lancedb/reranking/).
+
+<b>Late interaction</b> Late interaction is a technique that calculates the doc and query similarity independently and then the interaction or evaluation happens during the retrieval process. This is typically used in retrieval models like ColBERT. Unlike early interaction, It allows speeding up the retrieval process without compromising the depth of semantic analysis.
+
+## Internals of ColBERT 
+Let's take a look at the steps involved in performing late interaction based retrieval using ColBERT:
+
+• ColBERT employs BERT-based encoders for both queries `(fQ)` and documents `(fD)`
+• A single BERT model is shared between query and document encoders and special tokens distinguish input types: `[Q]` for queries and `[D]` for documents
+
+**Query Encoder (fQ):**
+• Query q is tokenized into WordPiece tokens: `q1, q2, ..., ql`. `[Q]` token is prepended right after BERT's `[CLS]` token
+• If query length < Nq, it's padded with [MASK] tokens up to Nq.
+• The padded sequence goes through BERT's transformer architecture
+• Final embeddings are L2-normalized.
+
+**Document Encoder (fD):**
+• Document d is tokenized into tokens `d1, d2, ..., dm`. `[D]` token is prepended after `[CLS]` token
+• Unlike queries, documents are NOT padded with `[MASK]` tokens
+• Document tokens are processed through BERT and the same linear layer
+
+**Late Interaction:**
+• Late interaction estimates relevance score `S(q,d)` using embedding `Eq` and `Ed`. Late interaction happens after independent encoding
+• For each query embedding, maximum similarity is computed against all document embeddings
+• The similarity measure can be cosine similarity or squared L2 distance
+
+**MaxSim Calculation:**
+```
+S(q,d) := Σ max(Eqi⋅EdjT)
+          i∈|Eq| j∈|Ed|
+```
+• This finds the best matching document embedding for each query embedding
+• Captures relevance based on strongest local matches between contextual embeddings
+
+## LanceDB MultiVector type
+LanceDB supports multivector type, this is useful when you have multiple vectors for a single item (e.g. with ColBert and ColPali).
+
+You can index on a column with multivector type and search on it, the query can be single vector or multiple vectors. For now, only cosine metric is supported for multivector search. The vector value type can be float16, float32 or float64. LanceDB integrateds [ConteXtualized Token Retriever(XTR)](https://arxiv.org/abs/2304.01982), which introduces a simple, yet novel, objective function that encourages the model to retrieve the most important document tokens first. 
+
+```python
+import lancedb
+import numpy as np
+import pyarrow as pa
+
+db = lancedb.connect("data/multivector_demo")
+schema = pa.schema(
+    [
+        pa.field("id", pa.int64()),
+        # float16, float32, and float64 are supported
+        pa.field("vector", pa.list_(pa.list_(pa.float32(), 256))),
+    ]
+)
+data = [
+    {
+        "id": i,
+        "vector": np.random.random(size=(2, 256)).tolist(),
+    }
+    for i in range(1024)
+]
+tbl = db.create_table("my_table", data=data, schema=schema)
+
+# only cosine similarity is supported for multi-vectors
+tbl.create_index(metric="cosine")
+
+# query with single vector
+query = np.random.random(256).astype(np.float16)
+tbl.search(query).to_arrow()
+
+# query with multiple vectors

+Often this key is a unique row id key. You can then specify what to do when
+there is a match and when there is not a match. For example, for upsert you want

+
+!!! tip "Use scalar indices to speed up merge insert"
+
+    The merge insert command needs to perform a join between the input data and the
+    target table on the `on` key you provide. This requires scanning that entire
+    column, which can be expensive for large tables. To speed up this operation,
+    you can create a scalar index on the `on` column, which will allow LanceDB to
+    find matches without having to scan the whole tables.

+    Read more about scalar indices in [Building a Scalar Index](../scalar_index.md)
+    guide.
+
+!!! info "Embedding Functions"
+
+    Like the create table and add APIs, the merge insert API will automatically

+    information.

-
-### Running lint / format
-
-LanceDb uses [biome](https://biomejs.dev/) for linting and formatting. if you are using VSCode you will need to install the official [Biome](https://marketplace.visualstudio.com/items?itemName=biomejs.biome) extension.
-To manually lint your code you can run:
-
-```sh
-npm run lint
-```
-
-to automatically fix all fixable issues:
-
-```sh
-npm run lint-fix
-```
-
-If you do not have your workspace root set to the `nodejs` directory, unfortunately the extension will not work. You can still run the linting and formatting commands manually.

+# Contributing to LanceDB Typescript
+
+This document outlines the process for contributing to LanceDB Typescript.
+For general contribution guidelines, see [CONTRIBUTING.md](../CONTRIBUTING.md).
+
+## Project layout
+
+The Typescript package is a wrapper around the Rust library, `lancedb`. We use
+the [napi-rs](https://napi.rs/) library to create the bindings between Rust and
+Typescript.
+
+* `src/`: Rust bindings source code
+* `lancedb/`: Typescript package source code
+* `__test__/`: Unit tests
+* `examples/`: An npm package with the examples shown in the documentation
+
+## Development environment
+
+To set up your development environment, you will need to install the following:
+
+1. Node.js 14 or later
+2. Rust's package manager, Cargo. Use [rustup](https://rustup.rs/) to install.
+3. [protoc](https://grpc.io/docs/protoc-installation/) (Protocol Buffers compiler)
+
+Initial setup:
+
+```shell
+npm install
+```
+
+### Commit Hooks
+
+It is **highly recommended** to install the [pre-commit](https://pre-commit.com/) hooks to ensure that your
+code is formatted correctly and passes basic checks before committing:
+
+```shell
+pre-commit install
+```
+
+## Development
+
+Most common development commands can be run using the npm scripts.
+
+Build the package
+
+```shell
+npm install
+npm run build
+```
+
+Lint:
+
+```shell
+npm run lint
+```
+
+Format and fix lints:
+
+```shell
+npm run lint-fix
+```
+
+Run tests:
+
+```shell
+npm test
+```
+
+To run a single test:
+
+```shell
+# Single file: table.test.ts
+npm test -- table.test.ts
+# Single test: 'merge insert' in table.test.ts
+npm test -- table.test.ts --testNamePattern=merge\ insert

+
+Create an IvfFlat index
+
+This index groups vectors into partitions of similar vectors.  Each partition keeps track of
+a centroid which is the average value of all vectors in the group.
+
+During a query the centroids are compared with the query vector to find the closest
+partitions.  The vectors in these partitions are then searched to find
+the closest vectors.
+
+The partitioning process is called IVF and the `num_partitions` parameter controls how
+many groups to create.
+
+Note that training an IVF FLAT index on a large dataset is a slow operation and
+currently is also a memory intensive operation.

+```ts
+whenMatchedUpdateAll(options?): MergeInsertBuilder
+```
+
+Rows that exist in both the source table (new data) and
+the target table (old data) will be updated, replacing
+the old row with the corresponding matching row.
+
+If there are multiple matches then the behavior is undefined.
+Currently this causes multiple copies of the row to be created
+but that behavior is subject to change.
+
+An optional condition may be specified.  If it is, then only
+matched rows that satisfy the condtion will be updated.  Any
+rows that do not satisfy the condition will be left as they
+are.  Failing to satisfy the condition does not cause a
+"matched row" to become a "not matched" row.
+
+The condition should be an SQL string.  Use the prefix
+target. to refer to rows in the target table (old data)
+and the prefix source. to refer to rows in the source
+table (new data).
+
+For example, "target.last_update < source.last_update"

+between them.  Unlike l2, the cosine distance is not affected by the
+magnitude of the vectors.  Cosine distance has a range of [0, 2].
+
+"dot" - Dot product. Dot distance is the dot product of two vectors. Dot
+distance has a range of (-∞, ∞). If the vectors are normalized (i.e. their
+l2 norm is 1), then dot distance is equivalent to the cosine distance.

+This value controls the tradeoff between build speed and accuracy.
+The higher the value the more accurate the build but the slower it will be.
+150 to 300 is the typical range. 100 is a minimum for good quality search
+results. In most cases, there is no benefit to setting this higher than 500.
+This value should be set to a value that is not less than `ef` in the search phase.
+

+

+
+```ts
+optional m: number;
+```
+
+The number of neighbors to select for each vector in the HNSW graph.
+
+The default value is 20.

+This value controls the tradeoff between search speed and accuracy.
+The higher the value the more accurate the search but the slower it will be.
+
+***
+
+### maxIterations?
+
+```ts
+optional maxIterations: number;
+```
+
+Max iterations to train kmeans.
+
+The default value is 50.
+
+When training an IVF index we use kmeans to calculate the partitions.  This parameter
+controls how many iterations of kmeans to run.
+
+Increasing this might improve the quality of the index but in most cases the parameter
+is unused because kmeans will converge with fewer iterations.  The parameter is only
+used in cases where kmeans does not appear to converge.  In those cases it is unlikely
+that setting this larger will lead to the index converging anyways.
+
+***
+
+### numPartitions?
+
+```ts
+optional numPartitions: number;
+```
+
+The number of IVF partitions to create.
+
+For HNSW, we recommend a small number of partitions. Setting this to 1 works
+well for most tables. For very large tables, training just one HNSW graph
+will require too much memory. Each partition becomes its own HNSW graph, so
+setting this value higher reduces the peak memory use of training.
+
+***
+
+### numSubVectors?
+
+```ts
+optional numSubVectors: number;
+```
+
+Number of sub-vectors of PQ.
+
+This value controls how much the vector is compressed during the quantization step.
+The more sub vectors there are the less the vector is compressed.  The default is
+the dimension of the vector divided by 16.  If the dimension is not evenly divisible
+by 16 we use the dimension divded by 8.
+
+The above two cases are highly preferred.  Having 8 or 16 values per subvector allows
+us to use efficient SIMD instructions.
+
+If the dimension is not visible by 8 then we use 1 subvector.  This is not ideal and
+will likely result in poor performance.
+
+***
+
+### sampleRate?
+
+```ts
+optional sampleRate: number;
+```
+
+The rate used to calculate the number of training vectors for kmeans.
+
+Default value is 256.
+
+When an IVF index is trained, we need to calculate partitions.  These are groups
+of vectors that are similar to each other.  To do this we use an algorithm called kmeans.
+
+Running kmeans on a large dataset can be slow.  To speed this up we run kmeans on a
+random sample of the data.  This parameter controls the size of the sample.  The total
+number of vectors used to train the index is `sample_rate * num_partitions`.
+
+Increasing this value might improve the quality of the index but in most cases the
+default should be sufficient.

+
+### maxIterations?
+
+```ts
+optional maxIterations: number;
+```
+
+Max iterations to train kmeans.
+
+The default value is 50.
+
+When training an IVF index we use kmeans to calculate the partitions.  This parameter
+controls how many iterations of kmeans to run.
+
+Increasing this might improve the quality of the index but in most cases the parameter
+is unused because kmeans will converge with fewer iterations.  The parameter is only
+used in cases where kmeans does not appear to converge.  In those cases it is unlikely
+that setting this larger will lead to the index converging anyways.
+
+***
+
+### numPartitions?
+
+```ts
+optional numPartitions: number;
+```
+
+The number of IVF partitions to create.
+
+For HNSW, we recommend a small number of partitions. Setting this to 1 works
+well for most tables. For very large tables, training just one HNSW graph
+will require too much memory. Each partition becomes its own HNSW graph, so
+setting this value higher reduces the peak memory use of training.

+
+### sampleRate?
+
+```ts
+optional sampleRate: number;
+```
+
+The rate used to calculate the number of training vectors for kmeans.
+
+Default value is 256.
+
+When an IVF index is trained, we need to calculate partitions.  These are groups
+of vectors that are similar to each other.  To do this we use an algorithm called kmeans.
+
+Running kmeans on a large dataset can be slow.  To speed this up we run kmeans on a
+random sample of the data.  This parameter controls the size of the sample.  The total
+number of vectors used to train the index is `sample_rate * num_partitions`.
+
+Increasing this value might improve the quality of the index but in most cases the
+default should be sufficient.

+
+### distanceType?
+
+```ts
+optional distanceType: "l2" | "cosine" | "dot" | "hamming";
+```
+
+Distance type to use to build the index.
+
+Default value is "l2".
+
+This is used when training the index to calculate the IVF partitions
+(vectors are grouped in partitions with similar vectors according to this
+distance type).
+
+The distance type used to train an index MUST match the distance type used
+to search the index.  Failure to do so will yield inaccurate results.
+
+The following distance types are available:
+
+"l2" - Euclidean distance. This is a very common distance metric that
+accounts for both magnitude and direction when determining the distance
+between vectors. l2 distance has a range of [0, ∞).
+
+"cosine" - Cosine distance.  Cosine distance is a distance metric
+calculated from the cosine similarity between two vectors. Cosine
+similarity is a measure of similarity between two non-zero vectors of an
+inner product space. It is defined to equal the cosine of the angle
+between them.  Unlike l2, the cosine distance is not affected by the
+magnitude of the vectors.  Cosine distance has a range of [0, 2].
+
+Note: the cosine distance is undefined when one (or both) of the vectors
+are all zeros (there is no direction).  These vectors are invalid and may
+never be returned from a vector search.
+
+"dot" - Dot product. Dot distance is the dot product of two vectors. Dot
+distance has a range of (-∞, ∞). If the vectors are normalized (i.e. their
+l2 norm is 1), then dot distance is equivalent to the cosine distance.
+
+"hamming" - Hamming distance. Hamming distance is a distance metric
+calculated from the number of bits that are different between two vectors.
+Hamming distance has a range of [0, dimension]. Note that the hamming distance
+is only valid for binary vectors.
+
+***
+
+### maxIterations?
+
+```ts
+optional maxIterations: number;

+
+Max iteration to train IVF kmeans.
+
+When training an IVF FLAT index we use kmeans to calculate the partitions.  This parameter
+controls how many iterations of kmeans to run.
+
+Increasing this might improve the quality of the index but in most cases these extra
+iterations have diminishing returns.
+
+The default value is 50.
+
+***
+
+### numPartitions?
+
+```ts
+optional numPartitions: number;
+```
+
+The number of IVF partitions to create.
+
+This value should generally scale with the number of rows in the dataset.
+By default the number of partitions is the square root of the number of
+rows.
+
+If this value is too large then the first part of the search (picking the
+right partition) will be slow.  If this value is too small then the second
+part of the search (searching within a partition) will be slow.
+
+***
+
+### sampleRate?
+
+```ts
+optional sampleRate: number;
+```
+
+The number of vectors, per partition, to sample when training IVF kmeans.
+
+When an IVF FLAT index is trained, we need to calculate partitions.  These are groups
+of vectors that are similar to each other.  To do this we use an algorithm called kmeans.
+
+Running kmeans on a large dataset can be slow.  To speed this up we run kmeans on a
