This page documents an earlier version of InfluxDB OSS.[InfluxDB 3 Core](/influxdb3/core/) is the latest stable version.

#### API token hashing is enabled by default in InfluxDB OSS 2.9.0

Stronger token security: tokens are stored as hashes on disk, so a
copy of the database file doesn’t expose usable tokens. Existing
tokens are hashed on first startup and the original strings can’t
be recovered afterward — **capture any plaintext tokens you still
need before you upgrade**.

For more information, see [Token hashing](/influxdb/v2/admin/tokens/#token-hashing).

The `influxd inspect build-tsi` command rebuilds the TSI index and, if necessary,
the series file.

## Usage

```sh
influxd inspect build-tsi [flags]
```

InfluxDB builds the index by reading all Time-Structured Merge tree (TSM) indexes
and Write Ahead Log (WAL) entries in the TSM and WAL data directories.
If the series file directory is missing, it rebuilds the series file.
If the TSI index directory already exists, the command will fail.

### Adjust performance

Use the following options to adjust the performance of the indexing process:

##### –max-log-file-size

`--max-log-file-size` determines how much of an index to store in memory before
compacting it into memory-mappable index files.
If you find the memory requirements of your TSI index are too high, consider
decreasing this setting.

##### –max-cache-size

`--max-cache-size` defines the maximum cache size.
The indexing process replays WAL files into a `tsm1.Cache`.
If the maximum cache size is too low, the indexing process will fail.
Increase `--max-cache-size` to account for the size of your WAL files.

##### –batch-size

`--batch-size` defines the size of the batches written into the index.
Altering the batch size can improve performance but may result in significantly
higher memory usage.
