Elasticsearch History API Infrastructure Upgrade
We have finally put native History node to rest in peace as so many have done already, since it became unwieldy and unstable.
We have consolidated 3 API servers into Elasticsearch cluster to support our new History API:
So far our Elasticsearch cluster is synchronized up to 31.2M blocks and processing 7 blocks per second on average, which means it should catch up with Head block in a few days time.
We are using best compression mechanism available on Elasticsearch and only storing data actually used by History API. For example: storing accounts and transactions but not storing blocks since blocks are available via standard chain API.
And yet the whole cluster is currently taking about 3TB space and growing every day.
The new History api is available on our standard API server: api.eostribe.io
