This opens up the door for more custom database implementations than the
two we have today. The biggest change should be inivisble:
`ConnectionInternal` has been renamed to `Database`, made public, and
refactored
However, there are a few breaking changes. `data_storage_version` and
`enable_v2_manifest_paths` have been moved from options on
`create_table` to options for the database which are now set via
`storage_options`.
Before:
```
db = connect(uri)
tbl = db.create_table("my_table", data, data_storage_version="legacy", enable_v2_manifest_paths=True)
```
After:
```
db = connect(uri, storage_options={
"new_table_enable_v2_manifest_paths": "true",
"new_table_data_storage_version": "legacy"
})
tbl = db.create_table("my_table", data)
```
BREAKING CHANGE: the data_storage_version, enable_v2_manifest_paths
options have moved from options to create_table to storage_options.
BREAKING CHANGE: the use_legacy_format option has been removed,
data_storage_version has replaced it for some time now

# Interface: CreateTableOptions
|
|
|
|
## Properties
|
|
|
|
### ~~dataStorageVersion?~~
|
|
|
|
```ts
|
|
optional dataStorageVersion: string;
|
|
```
|
|
|
|
The version of the data storage format to use.
|
|
|
|
The default is `stable`.
|
|
Set to "legacy" to use the old format.
|
|
|
|
#### Deprecated
|
|
|
|
Pass `new_table_data_storage_version` to storageOptions instead.
|
|
|
|
***
|
|
|
|
### embeddingFunction?
|
|
|
|
```ts
|
|
optional embeddingFunction: EmbeddingFunctionConfig;
|
|
```
|
|
|
|
***
|
|
|
|
### ~~enableV2ManifestPaths?~~
|
|
|
|
```ts
|
|
optional enableV2ManifestPaths: boolean;
|
|
```
|
|
|
|
Use the new V2 manifest paths. These paths provide more efficient
|
|
opening of datasets with many versions on object stores. WARNING:
|
|
turning this on will make the dataset unreadable for older versions
|
|
of LanceDB (prior to 0.10.0). To migrate an existing dataset, instead
|
|
use the LocalTable#migrateManifestPathsV2 method.
|
|
|
|
#### Deprecated
|
|
|
|
Pass `new_table_enable_v2_manifest_paths` to storageOptions instead.
|
|
|
|
***
|
|
|
|
### existOk
|
|
|
|
```ts
|
|
existOk: boolean;
|
|
```
|
|
|
|
If this is true and the table already exists and the mode is "create"
|
|
then no error will be raised.
|
|
|
|
***
|
|
|
|
### mode
|
|
|
|
```ts
|
|
mode: "overwrite" | "create";
|
|
```
|
|
|
|
The mode to use when creating the table.
|
|
|
|
If this is set to "create" and the table already exists then either
|
|
an error will be thrown or, if existOk is true, then nothing will
|
|
happen. Any provided data will be ignored.
|
|
|
|
If this is set to "overwrite" then any existing table will be replaced.
|
|
|
|
***
|
|
|
|
### schema?
|
|
|
|
```ts
|
|
optional schema: SchemaLike;
|
|
```
|
|
|
|
***
|
|
|
|
### storageOptions?
|
|
|
|
```ts
|
|
optional storageOptions: Record<string, string>;
|
|
```
|
|
|
|
Configuration for object storage.
|
|
|
|
Options already set on the connection will be inherited by the table,
|
|
but can be overridden here.
|
|
|
|
The available options are described at https://lancedb.github.io/lancedb/guides/storage/
