Bump version: 0.14.1-beta.0 → 0.14.1-beta.1

perf: eliminate iop in refresh (#1760 )
Closes #1741 If we checkout a version, we need to make a `HEAD` request to get the size of the manifest. The new `checkout_latest()` code path can skip this IOP. This makes the refresh slightly faster.

+### mergeInsert
+
+▸ **mergeInsert**(`on`, `data`, `args`): `Promise`\<`void`\>
+
+Runs a "merge insert" operation on the table
+
+This operation can add rows, update rows, and remove rows all in a single
+transaction. It is a very generic tool that can be used to create
+behaviors like "insert if not exists", "update or insert (i.e. upsert)",
+or even replace a portion of existing data with new data (e.g. replace
+all data where month="january")
+
+The merge insert operation works by combining new data from a
+**source table** with existing data in a **target table** by using a
+join.  There are three categories of records.
+
+"Matched" records are records that exist in both the source table and
+the target table. "Not matched" records exist only in the source table
+(e.g. these are new data) "Not matched by source" records exist only
+in the target table (this is old data)
+
+The MergeInsertArgs can be used to customize what should happen for
+each category of data.
+
+Please note that the data may appear to be reordered as part of this
+operation.  This is because updated rows will be deleted from the
+dataset and then reinserted at the end with the new values.
+
+#### Parameters
+
+| Name | Type | Description |
+| :------ | :------ | :------ |
+| `on` | `string` | a column to join on. This is how records from the source table and target table are matched. |
+| `data` | `Table`\<`any`\> \| `Record`\<`string`, `unknown`\>[] | the new data to insert |
+| `args` | [`MergeInsertArgs`](../interfaces/MergeInsertArgs.md) | parameters controlling how the operation should behave |

+# Interface: ColumnAlteration
+
+A definition of a column alteration. The alteration changes the column at
+`path` to have the new name `name`, to be nullable if `nullable` is true,
+and to have the data type `data_type`. At least one of `rename` or `nullable`
+must be provided.

+• `Optional` **nullable**: `boolean`

+### path
+
+• **path**: `string`
+
+The path to the column to alter. This is a dot-separated path to the column.
+If it is a top-level column then it is just the name of the column. If it is
+a nested column then it is the path to the column, e.g. "a.b.c" for a column
+`c` nested inside a column `b` nested inside a column `a`.

+• **mergeInsert**: (`on`: `string`, `data`: `Table`\<`any`\> \| `Record`\<`string`, `unknown`\>[], `args`: [`MergeInsertArgs`](MergeInsertArgs.md)) => `Promise`\<`void`\>
+
+#### Type declaration
+
+▸ (`on`, `data`, `args`): `Promise`\<`void`\>
+
+Runs a "merge insert" operation on the table
+
+This operation can add rows, update rows, and remove rows all in a single
+transaction. It is a very generic tool that can be used to create
+behaviors like "insert if not exists", "update or insert (i.e. upsert)",
+or even replace a portion of existing data with new data (e.g. replace
+all data where month="january")
+
+The merge insert operation works by combining new data from a
+**source table** with existing data in a **target table** by using a
+join.  There are three categories of records.
+
+"Matched" records are records that exist in both the source table and
+the target table. "Not matched" records exist only in the source table
+(e.g. these are new data) "Not matched by source" records exist only
+in the target table (this is old data)
+
+The MergeInsertArgs can be used to customize what should happen for
+each category of data.
+
+Please note that the data may appear to be reordered as part of this
+operation.  This is because updated rows will be deleted from the
+dataset and then reinserted at the end with the new values.
+
+##### Parameters
+
+| Name | Type | Description |
+| :------ | :------ | :------ |
+| `on` | `string` | a column to join on. This is how records from the source table and target table are matched. |

+### makeArrowTable
+
+▸ **makeArrowTable**(`data`, `options?`): `ArrowTable`
+
+An enhanced version of the makeTable function from Apache Arrow
+that supports nested fields and embeddings columns.
+
+This function converts an array of Record<String, any> (row-major JS objects)
+to an Arrow Table (a columnar structure)
+
+Note that it currently does not support nulls.
+
+If a schema is provided then it will be used to determine the resulting array
+types.  Fields will also be reordered to fit the order defined by the schema.
+
+If a schema is not provided then the types will be inferred and the field order
+will be controlled by the order of properties in the first record.
+
+If the input is empty then a schema must be provided to create an empty table.
+
+When a schema is not specified then data types will be inferred.  The inference
+rules are as follows:
+
+ - boolean => Bool
+ - number => Float64
+ - String => Utf8
+ - Buffer => Binary
+ - Record<String, any> => Struct
+ - Array<any> => List
+
+#### Parameters
+
+| Name | Type | Description |
+| :------ | :------ | :------ |
+| `data` | `Record`\<`string`, `any`\>[] | input data |
+| `options?` | `Partial`\<[`MakeArrowTableOptions`](classes/MakeArrowTableOptions.md)\> | options to control the makeArrowTable call. |
+
+#### Returns
+
+`ArrowTable`
+
+**`Example`**
+
+```ts
+
+import { fromTableToBuffer, makeArrowTable } from "../arrow";
+import { Field, FixedSizeList, Float16, Float32, Int32, Schema } from "apache-arrow";
+
+const schema = new Schema([
+  new Field("a", new Int32()),
+  new Field("b", new Float32()),
+  new Field("c", new FixedSizeList(3, new Field("item", new Float16()))),
+ ]);
+ const table = makeArrowTable([
+   { a: 1, b: 2, c: [1, 2, 3] },
+   { a: 4, b: 5, c: [4, 5, 6] },
+   { a: 7, b: 8, c: [7, 8, 9] },
+ ], { schema });
+```
+
+By default it assumes that the column named `vector` is a vector column
+and it will be converted into a fixed size list array of type float32.
+The `vectorColumns` option can be used to support other vector column
+names and data types.
+
+```ts
+
+const schema = new Schema([
+   new Field("a", new Float64()),
+   new Field("b", new Float64()),
+   new Field(
+     "vector",
+     new FixedSizeList(3, new Field("item", new Float32()))
+   ),
+ ]);
+ const table = makeArrowTable([
+   { a: 1, b: 2, vector: [1, 2, 3] },
+   { a: 4, b: 5, vector: [4, 5, 6] },
+   { a: 7, b: 8, vector: [7, 8, 9] },
+ ]);
+ assert.deepEqual(table.schema, schema);
+```
+
+You can specify the vector column types and names using the options as well
+
+```typescript
+
+const schema = new Schema([
+   new Field('a', new Float64()),
+   new Field('b', new Float64()),
+   new Field('vec1', new FixedSizeList(3, new Field('item', new Float16()))),
+   new Field('vec2', new FixedSizeList(3, new Field('item', new Float16())))
+ ]);
+const table = makeArrowTable([
+   { a: 1, b: 2, vec1: [1, 2, 3], vec2: [2, 4, 6] },
+   { a: 4, b: 5, vec1: [4, 5, 6], vec2: [8, 10, 12] },
+   { a: 7, b: 8, vec1: [7, 8, 9], vec2: [14, 16, 18] }
+ ], {
+   vectorColumns: {
+     vec1: { type: new Float16() },
+     vec2: { type: new Float16() }
+   }
+ }
+assert.deepEqual(table.schema, schema)
+```

Lance Release	5517e102c3	Bump version: 0.14.1-beta.0 → 0.14.1-beta.1	2024-10-23 00:33:40 +00:00
Will Jones	82197c54e4	perf: eliminate iop in refresh (#1760 ) Closes #1741 If we checkout a version, we need to make a `HEAD` request to get the size of the manifest. The new `checkout_latest()` code path can skip this IOP. This makes the refresh slightly faster.	2024-10-18 13:40:24 -07:00
Will Jones	48f46d4751	docs(node): update `indexStats` signature and regenerate docs (#1742 ) `indexStats` still referenced UUID even though in https://github.com/lancedb/lancedb/pull/1702 we changed it to take name instead.	2024-10-18 10:53:28 -07:00
