## Big In-Memory Keystores
|
|
|
|
The default maximum keystore limit for the In-Memory index is 2^24 of distinct terms/partials being stored (cardinality).
|
|
An additional register could be enabled and is dividing the index into self-balanced partitions.
|
|
The extended keystore is supported by any type of index.
|
|
|
|
```js
|
|
const index = new Index({
|
|
// e.g. set keystore range to 8-Bit:
|
|
// 2^8 * 2^24 = 2^32 keys total
|
|
keystore: 8
|
|
});
|
|
```
|
|
|
|
You can theoretically store up to 2^88 keys (64-Bit address range).
|
|
|
|
The internal ID arrays scales automatically when limit of 2^31 has reached by using Proxy.
|
|
|
|
> Persistent storages has no keystore limit by default.
|
|
> You should not enable keystore when using persistent indexes, as long as you do not stress the buffer too hard before calling `index.commit()`.
|
|
|
|
There is no additional memory cost when using a Keystore. |
