Previously, when we loaded the next version of the table, we would block all reads with a write lock. Now, we only do that if `read_consistency_interval=0`. Otherwise, we load the next version asynchronously in the background. This should mean that `read_consistency_interval > 0` won't have a meaningful impact on latency. Along with this change, I felt it was safe to change the default consistency interval to 5 seconds. The current default is `None`, which means we will **never** check for a new version by default. I think that default is contrary to most users expectations.
LanceDB JavaScript SDK
A JavaScript library for LanceDB.
Installation
npm install @lancedb/lancedb
This will download the appropriate native library for your platform. We currently support:
- Linux (x86_64 and aarch64 on glibc and musl)
- MacOS (Intel and ARM/M1/M2)
- Windows (x86_64 and aarch64)
Usage
Basic Example
import * as lancedb from "@lancedb/lancedb";
const db = await lancedb.connect("data/sample-lancedb");
const table = await db.createTable("my_table", [
{ id: 1, vector: [0.1, 1.0], item: "foo", price: 10.0 },
{ id: 2, vector: [3.9, 0.5], item: "bar", price: 20.0 },
]);
const results = await table.vectorSearch([0.1, 0.3]).limit(20).toArray();
console.log(results);
The quickstart contains a more complete example.
